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.

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.

Kilograms: A Unit of Weight

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.

Kilograms also can be marked as kilogrammes in UK.
