In various sources translated into Russian, one can often find mention of an ounce. It is a unit of mass, weight, or volume used in most British traditional systems of measurement. A typical avoirdupois ounce (approximately 28.3 grams) is 1/16 of the total weight of a pound.
This is a classic unit of measurement for the USA and Britain. It is mainly used in the United States of America when weighing packaged foods and portions, mailings, as well as to clarify the density of fabric and paper, boxing gloves, etc. It can sometimes be mentioned in the English-speaking sphere in other processes.

In addition to the regular one, several other ounces are currently in use. These can be measurements of different quantities. This unit is used not only to clarify the weight. It is used in such cases:
- A troy ounce weighing about 31.1 grams is used to determine the mass of precious metals such as gold, silver, platinum, palladium, rhodium, etc.
- An ounce-force is a measure of weight, that is, mass.
- A fluid ounce is a measure of volume.
Historically, it was used in many industries in various fields where it was required to measure mass or volume.
Name etymology
Where did the term "ounce" come from? This name comes from the Latin uncia - a unit that was one twelfth of the Roman pound (measure of weight).
The name was borrowed twice. At first, Old English was spoken "insan" or "indsan" (this is a corrupted form of Latin). Then, in late medieval English, the word "ounce" began to be used.
The abbreviation oz came later from the related Italian word onza (now spelled oncia).
Why there is no single standard
An ounce is a unit that is measured in many different ways. The explanation for this is as follows. It has been used historically in many parts of the world, in different moments history and for various applications. Therefore, unequal mass standards were taken as a basis.
How much does an ounce weigh in different meanings? The international version of avoirdupois calls 28.349523125 437.5 grams. An international troy ounce is 31.1034768480 grams, a French ounce is 30.59 grams. There are other numbers as well. About what types of this unit of measure are used in modern world, it is worth knowing more.
International avoirdupois system (oz)
An international ounce is 28.349523125 grams, according to the International Yard and Pound Convention of 1959. It was signed by the United States of America and the countries of the Commonwealth of Nations.
In the Avoirdupois system, sixteen ounces make up a pound with the same name. It is defined as follows: 7000 grains. Therefore, one ounce totals 437.5 grains.
It is still the standard unit of weight in the United States. In the UK, it ceased to be a legal unit of measure in 2000, but is still widely used on an informal basis. In addition, this is a traditional measure of portion sizes in British restaurants.

General information
Volume is the space occupied by a substance or object. Also, the volume can denote the free space inside the 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 for volume is the cubic metre. 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
It's like 0.001 cubic meters. The mass of one liter of water at 4°C is approximately equal to one kilogram. Often milliliters are also used, equal to one cubic centimeter or 1/1000 of a liter. A milliliter is usually referred to as ml.
jill
Gills are units of volume used in the United States to measure alcoholic beverages. One gill is five fluid ounces in the British imperial system, or four in the US. One American jill is equal to a quarter pint or half a cup. In Irish pubs, strong drinks are served in portions of a quarter of a jill, or 35.5 milliliters. The Scottish portions are smaller - one-fifth of a jill, or 28.4 milliliters. In England, until recently, servings were even smaller, only one-sixth of a jill or 23.7 milliliters. Now, it's 25 or 35 milliliters, depending on the rules of the institution. The hosts can decide for themselves which of the two servings to serve.
AMD
Dram, or drachma - a measure of volume, mass, as well as a coin. In the past, this measure was used in the pharmacy business and was equal to one teaspoon. Later, the standard volume of a teaspoon changed, and one spoon became equal to 1 and 1/3 drachmas.
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 weight.
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 the American system of measurement. This is approximately 4.93 milliliters. In American dietetics, the size of a teaspoon is 5 milliliters. In the UK it is common practice to use 5.9 milliliters, but some dietary guides and cookbooks use 5 milliliters. The volume of a teaspoon used in cooking is usually standardized in each country, but different sizes of spoons are used for eating.
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, about 14.7 milliliters, or 1/16 of an American cup. Tablespoons in the 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, a cup is not as strictly defined as spoons. The volume of the cup can vary from 200 to 250 milliliters. A metric cup is 250 milliliters, while an American cup is slightly smaller, about 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, respectively, 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 pints are not used to measure other liquids. In the UK, pints are used to measure milk and cider. 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 the gallon, and the gallon has a different volume depending on the country, pints are also not the same everywhere. An imperial pint is approximately 568.2 milliliters, while an American pint is 473.2 milliliters.
Fluid ounce
An imperial ounce is approximately equal to 0.96 US ounce. Thus, an imperial ounce contains approximately 28.4 milliliters, and an American ounce contains 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 liquid 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 values is the volume of the measured object. For example, if, when an object is lowered into a cup with one liter of water, the volume of liquid increases to two liters, then the volume of the object is one liter. In this way, only the volume of objects that do not absorb liquid can be calculated.
Formulas for calculating volume
Volume 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: edge length to the third power.
Ellipsoid: product of semiaxes and 4/3π.
Pyramid: one third of the product of the area of the base of the pyramid and the height.
Parallelepiped: product of length, width and height. If the height is unknown, then it can be calculated using the edge and the angle it makes with the base. If we call an edge A, corner A, length - l, and the width - w, then the volume of the parallelepiped V equals:
V = l w a cos( A)
This volume can also be calculated using the properties of right triangles.
Cone: radius squared times height and ⅓π.
Ball: radius to the third power multiplied by 4/3π.
Cylinder: the product of the area of the base of the cylinder, the height, and π: V=π r² h, where r is the radius of the cylinder and h is its height
The ratio between the volumes of cylinder:ball:cone is 3:2:1.

Many of you have certainly heard the word "ounce". But does everyone know what it means? It is outdated and not only. By the way, this concept has a rich history. And in some sectors of the economy, well, you can’t do without it. So how many grams does 1 ounce weigh?
Word
Without a doubt, this is a term of Latin origin. IN Ancient Rome so called one twelfth of the libra - the main measure of weight. However, not only the mass was measured with it. In general, it may seem that the Romans liked this word very much.
They often said: "I walked four ounces of the way to ..." or "I read three ounces of a book." What did it mean? Is it really possible to measure distance with a scale? Of course not. An ounce is another twelfth of something. Well, or one tenth or thirteenth - depending on the country and time. So what else was measured? And How? Also, an ounce in ancient Rome was called a coin. One dot was put on it when minted. The coin, of course, was of a small denomination. It was made from an alloy of tin, copper and lead. Some Spanish (doubloons) and Chinese gold coins were also called that.
Measures
So, an ounce is, of course, not only. It is also two and one - strength. In general, to find out the mass, there are several ounces. The Romans, as mentioned above, also used it to measure the length, area, capacity, and even the size of the inheritance. So, 1 ounce of length in ancient Rome was equal to 0.0246 meters. And the surface (area) there was measured by yugers. Accordingly, one twelfth of it - 1 ounce - is equal to 209.91 meters.
Varieties
The ancient Roman measure of weight - 1 ounce (one twelfth of a libra) was equal to 28.34 g. It seems quite a bit. But it was also divided into shares: semuncia, sicilicus, scrupules and siliquas. The latter were already 144 in an ounce.
Before the metric system of measures, the ounce was common throughout Europe. It is still in use today. However, not even all weights with this name are the same. Let's take a closer look at the most famous ones.
Troy ounce
There is probably more to say about this unit of measurement. It is currently used for weighing precious metals. It is also a unit when trading the latter on special exchanges.
There, prices for gold and other precious metals are determined precisely on the basis of one troy ounce. Its weight in terms of the metric system is approximately 31.103 grams. As you can see, it is different from an ordinary ounce. It is also used in jewelry and banking. It also measures the weight of valuable ingredients in cosmetology. But how did she appear?
The emergence of this term can be attributed to the thirteenth century AD. It will seem surprising to some, but this measure has nothing to do with the legendary city of Troy. And she appeared in the French Troyes. There at that time (12-13 centuries, and according to some sources - from the 5th century) three-month fairs became very popular, which attracted people from many European countries. The abundance of various currencies (in France then almost every city had its own money) and weights (each product had its own) created confusion in trade, and therefore after a while it was decided to take the French livre as a standard, which contained a pound of silver.
1 troy ounce, respectively, is one twelfth of this measure of weight. There is an opinion that this was not without the participation of the French crown. In any case, the unit seemed very convenient. After all, this coin weighed exactly a pound. And at that time, money was valued precisely for its weight. It was later that the precious metal in them began to be replaced with nickel or copper. However, kings have come and gone. And control over the chasers, of which there were quite a lot, was not always at a sufficient level. So silver became less and less. Very often, precious coins were cut off altogether in order to extract silver or gold. Therefore, it was necessary to introduce a standard coinage with a clear border. Over time, gold and silver, of course, significantly outgrew the value of the face value of all world coins. And they almost stopped adding them there.
coins
Currently, banks in many countries around the world continue to issue gold coins. Moreover, they are acquired not only for private collections. Thus, people can invest and store money in gold. In this sense, it is the equivalent of gold bars. Most of these coins contain just a troy ounce of gold:
1. Australian gold bar (coin).
2. Austrian Philharmonic.
3. American golden buffalo.
5. Canadian Gold Maple Leaf.
6. Chinese panda.
7. South African Krugerrand.
All of them have the corresponding inscription. And, of course, not all of them weigh exactly a troy ounce. They may also contain other metals. But a troy ounce of gold, silver or platinum must be in them. By the way, when buying precious metals via the Internet, be careful: in what units of measurement the weight is indicated there. After all, an ounce of avoirdupois (it is now most often used in trade) is lighter than a troy. As you can see, this seemingly outdated measure of weight does not even think of losing its position in this area to grams and kilograms. Perhaps this is because such a significant commodity as gold, for example, must also be measured in significant quantities. Yes, and it is easier to make ingots weighing 31 g than than one-gram ones. In general, using the example of a coin, you can perfectly and easily answer the question: "An ounce is how many grams of gold?"
American system of measures
In the United States, pounds are still used to measure weight. And with them, therefore, ounces. But again, not the same as everywhere else.
Averdupoix or the so-called trade ounce. It was used when selling goods by weight. In the metric system, its value is 28.349 g.
The American fluid ounce is used for It is equal to approximately 29.537 ml. When indicating the volume on packages with food products for convenience, it is equated to 30 milliliters. The British, by the way, have their own fluid ounce. Its volume is 28.413 ml.
European weights
Like many other things, the ounce was borrowed from the Roman Empire by almost all the peoples of Europe. And it was used everywhere until the introduction of the metric system in the eighteenth century. So, for example, in Germany it was considered one sixteenth of a trading pound. It was also used in medicine, where it was equal to 1/12 of a small pharmaceutical weight. She measured the weight in the preparation of medicines. The so-called apothecary ounce has survived to this day. Russia also adopted this system from the Germans. It weighed from 25 to 35 g - depending on the country where it was used. It is sometimes used even today. Therefore, when buying some foreign medicine in a pharmacy, it is important to know how many grams are in 1 ounce. An overdose is not necessary for you or your doctor.
In the Netherlands, they also used an ounce. And even when they switched to a new system in 1820, they retained their Dutch ounce to denote its weight of one hundred grams.
Other European countries did not lag behind. In Italy, there were 12 Roman ounces in a pound, and in Spain and Portugal, 16 each in Castilian libre and artel, respectively.
In England, there already existed the above-mentioned troy ounce, pharmaceutical and commercial. They were shares of the pounds of the same name. But if a troy and apothecaries are 1/12, then a trading ounce was equal to one sixteenth.
And once again about coins. In Sicily, until 1860, the ounce was in use. It was equal to two and a half scuds, three ducats. And it was equivalent to one hundred and twenty-three Italian lira of the new time.
On other continents
In addition to America, where the ounce took root in the United States, it also found its use in Africa. In the north of this continent it was called ukkiya. So, in Algeria, it corresponded to 34.13 grams, in Tunisia - 31.68, in Egypt - 37.068, and in Tripoli 1 ounce weighed 30.02 g.
Finally
So we learned what 1 ounce is equal to. And that it appeared in Ancient Rome. There it was used to measure not only weight, it was more of a mathematical symbol. From there she went to conquer the world. In many ways, the ounce anticipated the metric system in Europe. Only instead of one tenth, 1/12 appeared in Ancient Rome. This probably happened due to mythology. In the life of people then, the number twelve was quite symbolic.
Further, the ounce boldly marched across Europe, changing slightly, depending on the country. Then it was replaced by already more convenient kilograms and grams. But in the form of troy and avoirdupois, the ounce has reached our days. Probably because good things are hard to forget. After all, it became the first standard measure of weight in developing Europe. And largely thanks to her, the economies of the countries were able to develop correctly. It facilitated trade and became a measure of the most valuable commodity at that time - gold.
