## How to convert

1 carat (ct) = 0.0002 kilogram (kg). Carat (ct) is a unit of Weight used in Standard system. Kilogram (kg) is a unit of Weight used in Metric system.

## Carats: A Unit of Weight

Carats are a unit of weight that are used for measuring gemstones and pearls. Carats are derived from the Arabic word qirat, which means a small weight or a seed. The symbol for carat is ct.

## Definition of the Carat

The carat is defined as 200 milligrams, which is one fifth of a gram. The carat is divided into 100 points, which are each 2 milligrams. For example, a diamond that weighs 0.5 carat can also be expressed as 50 points or 100 milligrams.

The carat is not a legal unit of measurement in most countries, except for some that use the metric system, such as France, Belgium, Italy and Switzerland. In other countries, such as the United States, Canada, Australia and New Zealand, the carat is used as a standard unit for the diamond industry.

## How to Convert Carats

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

• To convert carats to ounces, divide by 141.7476. For example, 10 ct = 10 / 141.7476 = 0.071 oz.
• To convert carats to pounds, divide by 2267.962. For example, 20 ct = 20 / 2267.962 = 0.009 lb.
• To convert carats to tons (short), divide by 4535923.7. For example, 50 ct = 50 / 4535923.7 = 0.000011 ton.
• To convert carats to grams, divide by 5. For example, 100 ct = 100 / 5 = 20 g.
• To convert carats to kilograms, divide by 5000. For example, 200 ct = 200 / 5000 = 0.04 kg.
• To convert carats to milligrams, multiply by 200. For example, 25 ct = 25 x 200 = 5000 mg.

## Where Carats are Used

Carats are used in different countries and regions for different applications and purposes. Here are some examples of where carats are used:

• In most countries that use the metric system, carats are used for measuring gemstones and pearls, such as diamonds, rubies, sapphires, emeralds and pearls.
• In the United States, carats are used for measuring gemstones and pearls, especially for diamonds and diamond jewelry.
• In Canada, Australia and New Zealand, carats are used for measuring gemstones and pearls, especially for diamonds and diamond jewelry.
• In China, carats are used for measuring gemstones and pearls, especially for jade and jade jewelry.
• In India, carats are used for measuring gemstones and pearls, especially for gold and gold jewelry.

## History of Carats

Carats have a long history that dates back to ancient times. Here are some highlights of the history of carats:

• The carat was originally based on the weight of a carob seed, which was used as a counterweight in balance scales by ancient traders and jewelers. The carob seed was believed to have a uniform weight of about one fifth of a gram.
• The carat was used in different systems of measurement, such as the Roman system, the Byzantine system, the Arabic system and the Ottoman system. It varied from about 180 milligrams to about 220 milligrams depending on the region and the time period.
• The carat was standardized by international agreements in different periods of history. For example, in 1575 an agreement between France and England fixed the carat at 205 milligrams; in 1871 an agreement between Parisian jewelers fixed the carat at 205.3 milligrams; in 1907 an agreement between the International Committee of Weights and Measures fixed the carat at exactly 200 milligrams.

## 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.
