How to convert 1 carat (ct) = 3.086471671 grain (gr).
Carat (ct) is a unit of Weight used in Standard system.
Grain (gr) is a unit of Weight used in Standard 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.

Grains: A Unit of Weight
Grains are a unit of weight that are used for measuring small masses, such as bullets, arrows, and seeds. Grains are derived from the English word grain, which was the name of a seed or a cereal plant. The symbol for grain is gr.
Definition of the Grain
The grain is defined as one seven-thousandth of an avoirdupois pound, which is the common unit of weight in the US customary system and the British imperial system. The grain is equal to the troy grain, which is the smallest unit of the troy weight system, which is used for measuring precious metals. The grain is also equal to the apothecaries’ grain, which is the smallest unit of the apothecaries’ weight system, which is used for measuring medicines.
The grain is equal to about 0.0023 avoirdupois ounces or 0.0648 grams. The grain is also equal to about 0.00014 troy ounces or 0.0417 pennyweights.
How to Convert Grains
Grains can be converted to other units of weight by using conversion factors or formulas. Here are some examples of how to convert grains to other units of weight in the US customary system and the SI system:
- To convert grains to avoirdupois ounces, divide by 437.5. For example, 10 gr = 10 / 437.5 = 0.0229 oz.
- To convert grains to avoirdupois pounds, divide by 7000. For example, 5 gr = 5 / 7000 = 0.0007 lb.
- To convert grains to tons (short), divide by 14000000. For example, 20 gr = 20 / 14000000 = 0.0000014 ton.
- To convert grains to kilograms, divide by 15432.3584. For example, 15 gr = 15 / 15432.3584 = 0.000972 kg.
- To convert grains to grams, divide by 15.4323584. For example, 25 gr = 25 / 15.4323584 = 1.6218 g.

History of Grains
Grains have a long history that dates back to ancient times. Here are some highlights of the history of grains:
- The grain was originally based on the weight of a single seed of wheat or barley, which was used as a unit of mass in ancient civilizations such as Egypt, Mesopotamia and Greece.
- The grain was part of different systems of measurement, such as the Tower system, the Troy system, the Avoirdupois system and the Apothecaries’ system. It varied from about 40 milligrams to about 80 milligrams depending on the region and the time period.
- The grain was standardized by royal statutes and international agreements in different periods of history. For example, in 1527 an act of Henry VIII fixed the grain at exactly one seven-thousandth of an avoirdupois pound; 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.
