How to convert

1 troy ounce (oz t) = 0.031103477 kilogram (kg). Troy Ounce (oz t) is a unit of Weight used in Standard system. Kilogram (kg) is a unit of Weight used in Metric system.

Troy Ounces: A Unit of Weight

Troy ounces are a unit of weight that are used for measuring precious metals, such as gold, silver and platinum. Troy ounces are derived from the French word once, which was the name of a unit of weight used in the Middle Ages. The symbol for troy ounce is oz t.

Definition of the Troy Ounce

The troy ounce is defined as 20 pennyweights, which are each 24 grains. The troy grain is equal to the avoirdupois grain, which is one seven-thousandth of an avoirdupois pound. The troy ounce is heavier than the avoirdupois ounce, but lighter than the apothecaries’ ounce.

The troy ounce is equal to about 1.0971 avoirdupois ounces or 31.1035 grams. The troy grain is equal to about 0.0648 milligrams.

How to Convert Troy Ounces

Troy ounces can be converted to other units of weight by using conversion factors or formulas. Here are some examples of how to convert troy ounces to other units of weight in the US customary system and the SI system:

  • To convert troy ounces to avoirdupois ounces, multiply by 1.0971. For example, 10 oz t = 10 x 1.0971 = 10.971 oz.
  • To convert troy ounces to avoirdupois pounds, divide by 14.5833. For example, 5 oz t = 5 / 14.5833 = 0.343 lb.
  • To convert troy ounces to tons (short), divide by 29166.67. For example, 20 oz t = 20 / 29166.67 = 0.000685 ton.
  • To convert troy ounces to kilograms, divide by 32.1507. For example, 15 oz t = 15 / 32.1507 = 0.4666 kg.
  • To convert troy ounces to grams, multiply by 31.1035. For example, 25 oz t = 25 x 31.1035 = 777.5875 g.
  • To convert troy ounces to milligrams, multiply by 31103.4768. For example, 30 oz t = 30 x 31103.4768 = 933104.304 mg.

Where Troy Ounces are Used

Troy ounces are used in different countries and regions for different applications and purposes. Here are some examples of where troy ounces are used:

  • In most countries that use the SI system, troy ounces are not used for measuring weight, but only for measuring precious metals, such as gold, silver and platinum.
  • In the United States, troy ounces are used for measuring precious metals, especially for gold and silver coins and bullion.
  • In Canada, Australia and New Zealand, troy ounces are used for measuring precious metals, especially for gold and silver coins and bullion.
  • In the United Kingdom, troy ounces are used for measuring precious metals, especially for gold and silver coins and bullion.
  • In India, troy ounces are used for measuring precious metals, especially for gold and silver jewelry.

History of Troy Ounces

Troy ounces have a long history that dates back to ancient times. Here are some highlights of the history of troy ounces:

  • The troy ounce was originally based on the weight of a Roman uncia, which was one twelfth of a Roman libra or pound, which was equivalent to about 27 grams.
  • The troy ounce was used in different systems of measurement, such as the Roman system, the Byzantine system, the Arabic system and the English system. It varied from about 26 grams to about 32 grams depending on the region and the time period.
  • The troy ounce was standardized by royal statutes and international agreements in different periods of history. For example, in 1527 an act of Henry VIII fixed the troy ounce at exactly 480 grains; in 1828 an act of Congress adopted the troy ounce as the official unit of weight for coinage in the United States; in 1959 an international agreement defined the international avoirdupois ounce as exactly 28.349523125 grams, which made the troy ounce exactly 31.1034768 grams.

Example Conversions of Troy Ounces to Other Units

Here are some examples of conversions of troy ounces to other units of weight:

  • 1 oz t = 1.0971 oz
  • 1 oz t = 0.0686 lb
  • 1 oz t = 0.000034 ton
  • 1 oz t = 0.0311 kg
  • 1 oz t = 31.1035 g
  • 1 oz t = 31103.4768 mg
  • 1 oz t = 0.0833 lb t
  • 1 oz t = 20 dwt
  • 1 oz t = 480 gr

Kilograms: A Unit of Weight

Definition of the Kilogram

A kilogram is a unit of weight that measures how much force an object or substance exerts on a scale due to gravity. It is equal to the mass of the International Prototype of the Kilogram (IPK), a cylinder of platinum-iridium alloy stored at the International Bureau of Weights and Measures in France. One kilogram can also be written as kg or 1000 g.

History of the Kilogram

The kilogram was originally defined in 1795 during the French Revolution as the mass of one litre of water at 4 °C, which was determined to be 18841 grains. In 1799, the Kilogramme des Archives, a platinum artifact, replaced it as the standard of weight. In 1889, the IPK became the new standard of the unit of weight for the metric system and remained so for 130 years, until the current definition was adopted in 2019.

The kilogram, as well as other metric units of weight, such as the gram and the tonne, were introduced in the 19th century as part of the decimal system of measurement that aimed to simplify and unify the units used in science and commerce. The kilogram was officially adopted by the International System of Units (SI) in 1960 as one of the seven base units.

How to Convert Kilograms

To convert kilograms to other units of weight, we need to use conversion factors that relate the kilogram to the desired unit. For example, to convert kilograms to pounds, we need to know that one pound is equal to 0.45359237 kg. Therefore, one kilogram is equal to 2.2046226218 pounds.

Here are some common conversion factors for kilograms:

  • 1 kg = 1000 g
  • 1 kg = 2.2046226218 lb
  • 1 kg = 35.27396195 oz
  • 1 kg = 0.001 t
  • 1 kg = 0.1574730444 st

To convert from other units of weight to kilograms, we need to use the inverse of these conversion factors. For example, to convert pounds to kilograms, we need to divide by 2.2046226218.

Where Kilograms are Used

The kilogram is a unit of weight that is widely used to measure the weight of objects and substances such as food, clothes, animals, metals and chemicals. For example, an adult human body has an average weight of about 62 kg.

The kilogram is also used to measure the weight of some physical quantities such as force, pressure and torque. For example, one newton (N) is equal to one kilogram times one meter per second squared (kg x m/s2).

Example Conversions of Kilograms to Other Units

Here are some examples of how to convert kilograms to other units of weight using the conversion factors given above:

  • 2 kg = 2 x 1000 g = 2000 g
  • 3 kg = 3 x 2.2046226218 lb = 6.6138678654 lb
  • 4 kg = 4 x 35.27396195 oz = 141.0958478 oz
  • 5 kg = 5 x 0.001 t = 0.005 t
  • 6 kg = 6 x 0.1574730444 st = 0.9448382664 st

Conclusion

The kilogram is a unit of weight that measures how much force an object or substance exerts on a scale due to gravity. It is equal to the mass of the IPK, a cylinder of platinum-iridium alloy stored in France. The kilogram is widely used to measure the weight of objects and substances such as food, clothes, animals, metals and chemicals, as well as some physical quantities such as force, pressure and torque. To convert kilograms to other units of weight, we need to use conversion factors that relate the kilogram to the desired unit.

Kilograms also can be marked as kilogrammes in UK.
