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.

An Introduction to US Short Hundredweights

US short hundredweights are a unit of weight in the US customary system that are equal to 100 pounds. They are also known as centals or simply hundredweights, and are commonly used for measuring the quantities of some agricultural products or industrial materials. In this article, we will explore the definition, history, conversion and usage of US short hundredweights.

Definition of US Short Hundredweights

A US short hundredweight is a unit of weight in the US Customary System equal to 100 pounds (45.36 kilograms). The symbol for US short hundredweight is cwt, and it is derived from the Latin word centum, meaning “hundred”. A US short hundredweight is also equivalent to 45.359237 kilograms, 0.05 US short tons or 0.045359237 metric tons.

History of US Short Hundredweights

US short hundredweights were introduced as a unit of measurement in the US and Canada in the late 18th or early 19th century, as a way to simplify the trading of some goods between countries. They were based on the British imperial system, which defined one hundredweight as 112 pounds. However, since the British hundredweight was too heavy for some purposes, such as measuring grains or livestock, the US and Canada adopted a lighter version of 100 pounds.

The US short hundredweight was also influenced by the French metric system, which was introduced in 1795 and used a base-ten system of units. The French system had a unit of mass called the quintal, which was equal to 100 kilograms or 220.462 pounds. The US short hundredweight was similar to the quintal, but slightly lighter.

The US short hundredweight was officially recognized by the US government in 1836, when it passed a law that defined one bushel of wheat as 60 pounds and one barrel of flour as 196 pounds. These measures were based on the US short hundredweight of 100 pounds.

The use of the US short hundredweight as a measurement has declined in recent years in favor of the metric system or other units such as pounds or tons. However, it is still used for some commodities such as grains, oilseeds, paper, and concrete additives.

How to Convert US Short Hundredweights

US short hundredweights can be easily converted to other units of weight by multiplying or dividing by appropriate factors. For example, to convert US short hundredweights to pounds, we multiply by 100; to convert US short hundredweights to kilograms, we multiply by 45.359237; to convert US short hundredweights to tons, we divide by 20.

Where US Short Hundredweights are Used

US short hundredweights are commonly used for measuring the quantities of some agricultural products or industrial materials in the US and Canada. Here are some examples:

• In agriculture, US short hundredweights are used for measuring the weight of grains such as wheat, corn, oats, barley, rye, and rice; oilseeds such as soybeans, canola, sunflower seeds, and flax seeds; hay and straw; sugar beets; and potatoes.
• In industry, US short hundredweights are used for measuring the weight of paper products such as newsprint, printing paper, tissue paper, and cardboard; concrete additives such as cement and fly ash; and steel products such as bars, rods, plates, and sheets.
• In commerce, US short hundredweights are used for pricing some commodities on futures exchanges such as the Chicago Board of Trade (CBOT) and the Minneapolis Grain Exchange (MGEX). For example, wheat futures contracts are quoted in cents per bushel based on a contract size of 5,000 bushels or 136 metric tons or 3,000 cwt.

Example Conversions of US Short Hundredweights to Other Units

Here are some example conversions of US short hundredweights to other units:

• To convert 2 cwt to lb, we multiply by 100: 2 cwt x 100 = 200 lb
• To convert 5 cwt to kg, we multiply by 45.359237: 5 cwt x 45.359237 = 226.796185 kg
• To convert 3 cwt to t, we divide by 20: 3 cwt / 20 = 0.15 t
