Troy ounce of gold in grams. Volume and unit converter for recipes
Gold is a precious metal that has several units of measurement depending on the territory. It is difficult for beginners to navigate the transfer of one unit to another. Therefore, people have a question: how much will an ounce of gold weigh in grams? Units of measurement are needed to determine the exact weight of the precious metal. The most popular among them:
- Grams. This unit of measurement is international, but, unfortunately, it has not taken root in all countries.
- Ounces. Even though the measurement system is quite old, it still exists, especially in relation to the weight of precious metals. And the question of that is still relevant.
- Carat and fineness are not units of weight. This is simply a measure of the amount of gold in the piece of jewelry and is expressed as a percentage or carat. Knowing this value and how much the jewelry weighs, you can calculate the mass of pure gold contained in it.
How the amount of gold is measured depends on tradition. In some countries, they use ounces more when measuring any product, including gold.
Origin of the ounce
A troy ounce of gold in grams is equal to the value of 31.1035, which is often rounded to the nearest 31 grams. It so happened that in jewelry, cosmetics and banking, up to today by weight is determined in ounces.
It all started in the 12th century in the town of Troyes on the banks of the Seine. It was there that the largest fairs in Europe were held, in which traders and merchants from different countries. And so there was confusion in monetary processes, since currency exchange rates simply did not exist at that time.
And all the coins, one way or another, were made of precious metals, so the weight of the French livre, which corresponded to one troy pound of silver, was taken as the basis for calculations. Thus, it began to gain popularity and soon conquered the world of precious metals: now gold is most often measured with its help. Therefore, the origin of the name has nothing to do with Troy, and writing “Trinity ounce” is incorrect.
A troy ounce is comparable in weight to one-twelfth of an English gold coin pound. 1 ounce of gold weighs the same as some coins:
- Canadian gold maple leaf;
- American Golden Eagle;
- American golden buffalo;
- Australian (this is not an ordinary gold bar).
In addition, we should not forget that, in addition to the troy ounce, there are several other types:
- an ounce of avoirdupois, its weight is 28.34 grams;
- pharmaceutical ounce, which existed in Russia and is equivalent to 26.89 grams;
- ounce in grams of Maria Teresa is equal to 31.10.
Despite the fact that the numbers are close to each other, the troy ounce is still the main one in bank calculations for the purchase/sale of gold, and it is in it that the precious metal will continue to be measured. Therefore, when purchasing, it is necessary to clarify the weight measure, since even the slightest differences in milligrams will affect the cost. The price per ounce of the precious metal is expressed in US dollars, since the dollar is the world's reserve currency.
Troy ounce
How is the price of an ounce of gold determined?
Mass, as well as two measures of volume of liquid bodies, one unit of force and several monetary units formed as the twelfth of another unit. The term comes from ancient Rome, where an ounce meant the twelfth of a libra. Was one of the main weight units medieval Europe. Today it is used when trading precious metals - troy ounce, as well as in countries where weight is measured in pounds (for example, the USA).
Ancient Rome
Among the ancient Romans, 1/12 of a unit of weight was called libra (lat. libra) or ass and weighed 327.45 g (0.7996 Russian pounds or 76 spools 73 shares), and corresponded to 28.34 g (0.0666 Russian pounds or 6.394 spools). In turn, the ounce was divided into 2 semuntia, 4 sicilicus, 6 sextuli, 24 scrupules and 144 siliqua. The ounce was designated by a dot ( · ) or (on coins) in the form of a small convex hemisphere, sometimes with a horizontal line ( - ), and also (in cursive) with the signs and; ½ ounce (semuntia) was designated by the signs Σ , Є , £ , Sicilian - Ɔ , sextools - 𐆓 , scrupula - ℈ . The Romans used this system of duodecimal division of units for various purposes: for example, the ounce and its multiple designations were defined:
- size of inheritance
- measures of length (ounce = 1/12 Roman foot = 0.0246 m = 9685 lines)
- surface measures (ounce = 1/12 yugra = 2400 Roman square feet = 46 square fathoms, 6 square feet, 72 square inches = 209.91 m²)
- capacity measures (ounce = cyatou = 1/12 sextary = 0.0372 cups)
- banknotes (ounce = 1/12 asses) - while asses were more often used in circulation, containing instead of twelve an average of 10 ounces (from 11 to 9) - 272.88 g = 0.666 Russian pounds. As currency, ounces were minted from copper, with an admixture of 7% tin and 23.6% lead; on one side the head of Minerva (or the goddess of Rome) was depicted, on the other - the coat of arms of the city.
Uncial division was used by the Romans in fractional calculations. Just like in decimals The first place after the decimal point is occupied by tenths, the second by hundredths, and so on; among the Romans, fractions were expressed in series of quantities in which the denominator was a multiple of 12, with the first place being occupied by ounces, the second by semuntia, and so on.
Use of the ounce before the introduction of the metric system of measures
The ounce was borrowed from the Romans by almost everyone European peoples and before introduction metric system measures were the most common unit of weight in the world. In Germany, an ounce was equal to 1/16 of a large trade pound (= 1/8 of a mark) and 1/12 of a small apothecary's weight, which was only replaced by the metric system in 1872. From Germany, an ounce appeared in Russian pharmacies. In Italy it was equal to 1/12 of a pound, in Spain and Portugal = 1/16 of a trade (avoirdupois) pound. An ounce was also called in Sicily (until 1865) a monetary unit equal to 2½
In our turbulent times, one of the most important indicators of the reliability of the economic condition of a country is the totality of its gold reserves. When talking about the value of this yellow metal in one currency or another, they use a rather strange measure called the troy ounce of gold. For some reason, the cost of this metal is not reflected in grams. How did this happen, why is the universal weight unit not used when weighing gold? And how much does a troy ounce weigh in grams?
What is an "ounce"
The concept of the ounce was born in Ancient Rome. In those days, bronze coins were in circulation, which were divided into parts. The twelfth part of a bronze ancient Roman coin was called an ounce. In modern equivalent, its weight was just over 27 grams.
Over time, the ounce began to be used not only as currency unit. Since Rome had fairly strict standards for minting coins, ounces became convenient for weighing small measures of various substances. The price of gold has always been high, so the ounce was the best choice for weighing this metal. Over time, this small measure of scales spread throughout Europe.
How to convert troy ounce to grams
Converting troy ounces to grams is quite simple. It should be remembered that one troy ounce is equal to 31.1035 grams. Accordingly, to convert, you should multiply this value by the required number of ounces.

General information
Volume is the space occupied by a substance or object. Volume can also refer to the free space inside a container. Volume is a three-dimensional quantity, unlike, for example, length, which is two-dimensional. Therefore, the volume of flat or two-dimensional objects is zero.
Volume units
Cubic meter
The SI unit of volume is the cubic meter. The standard definition of one cubic meter is the volume of a cube with edges one meter long. Derived units such as cubic centimeters are also widely used.
Liter
The liter is one of the most commonly used units in the metric system. It is equal to the volume of a cube with edges 10 cm long:
1 liter = 10 cm × 10 cm × 10 cm = 1000 cubic centimeters
This is the same as 0.001 cubic meters. The mass of one liter of water at a temperature of 4°C is approximately equal to one kilogram. Milliliters, equal to one cubic centimeter or 1/1000 of a liter, are also often used. Milliliter is usually denoted as ml.
Jill
Jills are units of volume used in the US to measure alcoholic drinks. One jill is five fluid ounces in the British Imperial system or four in the American system. One American jill is equal to a quarter of a pint or half a cup. Irish pubs serve strong drinks in portions of a quarter jill, or 35.5 milliliters. In Scotland, portions are smaller - one fifth of a jill, or 28.4 milliliters. In England, until recently, portions were even smaller, just one-sixth of a jill or 23.7 milliliters. Now, it’s 25 or 35 milliliters, depending on the rules of the establishment. The owners can decide for themselves which of the two portions to serve.
Dram
Dram, or drachma, is a measure of volume, mass, and also a coin. In the past, this measure was used in pharmacy and was equal to one teaspoon. Later, the standard volume of a teaspoon changed, and one spoon became equal to 1 and 1/3 drachms.
Volumes in cooking
Liquids in cooking recipes are usually measured by volume. Bulk and dry products in the metric system, on the contrary, are measured by mass.
Tea spoon
The volume of a teaspoon varies different systems measurements. Initially, one teaspoon was a quarter of a tablespoon, then - one third. It is the latter volume that is now used in American system measurements. This is approximately 4.93 milliliters. In American dietetics, the size of a teaspoon is 5 milliliters. In the UK it is common to use 5.9 millilitres, but some diet guides and cookbooks- this is 5 milliliters. The size of a teaspoon used in cooking is usually standardized in each country, but different sizes of spoons are used for food.
Tablespoon
The volume of a tablespoon also varies depending on the geographic region. So, for example, in America, one tablespoon is three teaspoons, half an ounce, approximately 14.7 milliliters, or 1/16 of an American cup. Tablespoons in UK, Canada, Japan, South Africa and New Zealand - also contain three teaspoons. So, a metric tablespoon is 15 milliliters. A British tablespoon is 17.7 milliliters, if a teaspoon is 5.9, and 15 if a teaspoon is 5 milliliters. Australian tablespoon - ⅔ ounce, 4 teaspoons, or 20 milliliters.
Cup
As a measure of volume, cups are not defined as strictly as spoons. The volume of the cup can vary from 200 to 250 milliliters. A metric cup is 250 milliliters, and an American cup is slightly smaller, approximately 236.6 milliliters. In American dietetics, the volume of a cup is 240 milliliters. In Japan, cups are even smaller - only 200 milliliters.
Quarts and gallons
Gallons and quarts also have different sizes depending on the geographic region where they are used. In the Imperial system of measurement, one gallon is equal to 4.55 liters, and in the American system of measurements - 3.79 liters. Fuel is generally measured in gallons. A quart is equal to a quarter of a gallon and, accordingly, 1.1 liters in the American system, and approximately 1.14 liters in the Imperial system.
Pint
Pints are used to measure beer even in countries where the pint is not used to measure other liquids. In the UK, milk and cider are measured in pints. A pint is equal to one-eighth of a gallon. Some other countries in the Commonwealth of Nations and Europe also use pints, but since they depend on the definition of a gallon, and a gallon has a different volume depending on the country, pints are also not the same everywhere. An imperial pint is approximately 568.2 milliliters, and an American pint is 473.2 milliliters.
Fluid ounce
An imperial ounce is approximately equal to 0.96 US ounces. Thus, an imperial ounce contains approximately 28.4 milliliters, and an American ounce contains approximately 29.6 milliliters. One US ounce is also approximately equal to six teaspoons, two tablespoons, and one eighth cup.
Volume calculation
Liquid displacement method
The volume of an object can be calculated using the fluid displacement method. To do this, it is lowered into a liquid of a known volume, a new volume is geometrically calculated or measured, and the difference between these two quantities is the volume of the object being measured. For example, if when you lower an object into a cup with one liter of water, the volume of the liquid increases to two liters, then the volume of the object is one liter. In this way, you can only calculate the volume of objects that do not absorb liquid.
Formulas for calculating volume
The volume of geometric shapes can be calculated using the following formulas:
Prism: the product of the area of the base of the prism and the height.
Rectangular parallelepiped: product of length, width and height.
Cube: length of an edge to the third power.
Ellipsoid: product of semi-axes and 4/3π.
Pyramid: one third of the product of the area of the base of the pyramid and the height. Post a question in TCTerms and within a few minutes you will receive an answer.
Gold reserves are one of the indicators of a country’s well-being, a symbolic guarantor of its economic and social well-being. Today, about more than 90% of the world's gold reserves are stored in the form of gold bars in special storage facilities of states. The United States, Italy, France, Germany and China have the largest reserves of monetary gold. The United States remains the undisputed leader in gold bullion reserves. However, gold today is also the property of private individuals. But who is the richest owner is not known for certain. As a version - this is one of royal families East.
Why are gold reserves needed?
The natural question is why are gold reserves so important? Why did this precious metal become the cornerstone in the emerging global economic system?
Firstly, the presence of significant gold reserves allows the state to maintain economic independence from other currencies. Secondly, gold is still one of the reliable ways investment investments. Over the last decade alone, the value of this yellow metal has increased more than 5 times. In the event of an unstable economic situation in the domestic market of the state, threatening inflation of the national currency, gold will be able to serve as a kind of monetary equivalent recognized throughout the world.
Investments in gold: profitable or not?
In 2005, Rick Munaritz, one of the co-owners of the Internet service, faced a dilemma: what is more reliable to invest his money in? search engine Google or gold. At that time, their prices on the stock exchange were the same. But in 2008, the crisis struck and trading in Google closed at $307 per share, and in gold at $866 per ounce.
To the origins of history
But what is such a strange measure - a troy ounce of gold? Why is the universal unit of weight, grams, not used when weighing gold? And what is the ratio of these two units of measurement. How much is a troy ounce in grams? Let's try to understand the essence of this issue.
An ounce is nothing more than a twelfth of the ancient Roman bronze coin “assi”. The Romans used large bronze coins cut into pieces as money. Over time, this monetary unit began to be used as a measure of weight. It owes this to the Romans’ pedantic attitude towards coinage. There was no doubt about their compliance with coinage standards. How much does a troy ounce weigh in grams? You will learn about this later. First, a little history.
Let's make a reservation right away, ancient city Troy has nothing to do with this unit of measurement. The troy ounce owes its name to the small town of Troyes. In the twelfth century, fairs were held here, in which merchants from all over the world participated. That is why the need for a single universal measure arose. The diversity of national currencies already available at that time somewhat complicated the establishment of trade relations. Preference was given to the French livre. It consisted of a troy pound of silver, which, in turn, was divided into twelve troy ounces. Since then, the troy ounce has been gaining popularity and successfully adapted to the realities of the time. Especially for measuring the weight of expensive and valuable materials. Troy ounce - how many grams? It's time to find out about it.
How much does an ounce weigh?
How much does a troy ounce of gold weigh? In grams in Ancient Rome its weight was 27.288. After the disappearance of the Roman Empire, there was no single standard for the minting of bronze coins, and therefore the ounce somewhat lost its infallibility. Her weight in different areas began to differ noticeably. And this, in turn, became the subject of a dispute between the buyer and seller. The introduction of the metric system of units made it possible to determine how much a troy ounce of gold weighs in grams. Today one ounce weighs 31.1034768 grams.
Purity standards or how many precious metals are in valuable coins?
Today, the ounce is the primary measurement in precious metals trading: it measures the weight of bullion or bullion coins (gold, silver, palladium and platinum) issued by central banks.
What is the current ratio "USD - troy ounce"? For example, in the USA, coins were made from gold weighing 1/10 of a troy ounce, corresponding to a denomination of 5 dollars; 25 dollars corresponded to a coin weighing ½ troy ounce, 50 dollars corresponded to a coin weighing 1 ounce. Classic option, are undeniably American Eagles - they contain one ounce of high-grade platinum.
In Russia, the weight of coins made of precious metals is indicated in grams, but the amount of precious metal is indicated in fractions of a troy ounce. The weight of the 50 ruble St. George the Victorious gold coin issued by the Bank of Russia weighs -7.89 grams, the weight of pure gold is at least 7.78 grams, which is ¼ troy ounce.
How much does an ounce cost?
What is a troy ounce? How many grams are in it? We've already dealt with this. All that remains is to find out how much an ounce costs? How is the price of gold formed? There is a reliable and time-tested practice of fixing gold. This tradition began in September 1919 in London. On September 3, 1939, due to the cessation of gold trading, the fixing procedure was discontinued. London trading resumed on March 22, 1954 and has not undergone significant changes since then. Within a minute, trading participants are ready to answer the question of whether the price of gold is rising or falling. If the number of buyers exceeds the number of sellers, the initial price of gold rises. This procedure is carried out in London at LBM auctions twice a day: at 10.30 am and three o'clock in the afternoon. It is believed that the price level for precious metals established by the London fixing is the fairest.
How much is gold today?
The dynamics of changes in the price of gold are of great interest not only to those who have chosen it as an object of investment. This is a kind of indicator of the state of the world economy. So, let's analyze how the gold rate changed over the last years. In 1996, one ounce of gold cost about $400; already in 2010-2011, the price per ounce of gold rose to $1,300. During this time interval the increase was almost 30%. According to analysts, 2015 was not so good for the precious metals market. The cost of one ounce fell from $1,000 in 2014 to $840 in 2015. And in 2016 there are quite convincing preconditions for an increase in the price of the yellow metal.
Finally
If you have finally decided to invest in physical gold, the ideal solution would be to purchase gold bars from one of the state banking institutions. If you make a transaction over the Internet, be careful. The fact is that there are two types of ounce: troy ounce and avoirdupois ounce. The substitution of concepts has already played a cruel joke on more than one entrepreneur. A troy ounce of gold is almost 9.7% heavier in grams. Good luck with your investment.
