How to convert 1 carat (ct) = 0.2 gram (g).
Carat (ct) is a unit of Weight used in Standard system.
Gram (g) 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.

Grams: A Unit of Weight
Grams are a unit of weight that are used in the International System of Units (SI), also known as the metric system. Grams are derived from the French word gramme, which was taken from the Late Latin term gramma, meaning a small weight. The symbol for gram is g.
Definition of the Gram
The gram is defined as one one-thousandth of a kilogram, which is the base unit of mass in the SI. The kilogram is defined by taking the fixed numerical value of the Planck constant h to be 6.62607015 ×10 −34 when expressed in the unit J s, which is equal to kg m 2 s −1, where the meter and the second are defined in terms of c and ∆ν Cs. The Planck constant is a fundamental physical constant that relates the energy of a photon to its frequency.
The gram is a very small unit of weight, equivalent to about 0.035 ounces or 0.002 pounds. It is commonly used for measuring non-liquid ingredients in cooking, such as flour, sugar, salt and spices. It is also used for measuring small masses, such as jewelry, coins, medicines and chemicals.
How to Convert Grams
Grams can be converted to other units of weight by using conversion factors or formulas. Here are some examples of how to convert grams to other units of weight in the US customary system and the SI system:
- To convert grams to ounces, divide by 28.349523125. For example, 100 g = 100 / 28.349523125 = 3.527 oz.
- To convert grams to pounds, divide by 453.59237. For example, 500 g = 500 / 453.59237 = 1.102 lb.
- To convert grams to tons (short), divide by 907184.74. For example, 1000 g = 1000 / 907184.74 = 0.0011 ton.
- To convert grams to kilograms, divide by 1000. For example, 200 g = 200 / 1000 = 0.2 kg.
- To convert grams to milligrams, multiply by 1000. For example, 50 g = 50 x 1000 = 50000 mg.
- To convert grams to micrograms, multiply by 1000000. For example, 10 g = 10 x 1000000 = 10000000 µg.
Where Grams are Used
Grams are used in different countries and regions for different applications and purposes. Here are some examples of where grams are used:
- In most countries that use the SI system, grams are used for measuring food portions and ingredients, postal items, drugs and medicines, precious metals and gems and scientific experiments.
- In the United States, grams are sometimes used for measuring food portions and ingredients, especially for nutritional information labels, drugs and medicines, precious metals and gems and scientific experiments.
- In Canada, grams are used for measuring food portions and ingredients, postal items, drugs and medicines, precious metals and gems and scientific experiments.
- In Australia and New Zealand, grams are used for measuring food portions and ingredients, postal items, drugs and medicines, precious metals and gems and scientific experiments.
- In China, grams are used for measuring food portions and ingredients, postal items, drugs and medicines, precious metals and gems and scientific experiments.
History of Grams
Grams have a long history that dates back to ancient times. Here are some highlights of the history of grams:
- The gram was originally defined in 1795 as the absolute weight of a volume of pure water equal to the cube of the hundredth part of a meter at the temperature of melting ice.
- The gram was later changed to be the weight of a volume of pure water equal to the cube of the hundredth part of a meter at the temperature of maximum density of water (4 °C).
- The gram was part of the centimeter–gram–second system of units (CGS) that was developed in the 19th century as an alternative to the meter–kilogram–second system of units (MKS).
- The gram was replaced by the kilogram as the base unit of mass in the SI system that was adopted in 1960 as an international standard for measurements.
- The gram was redefined in terms of the kilogram and the Planck constant in 2019 as part of a major revision of the SI system.
