Kilograms: A Unit of Weight

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.

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.

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.
• To convert grains to milligrams, multiply by 64.79891. For example, 30 gr = 30 x 64.79891 = 1943.9673 mg.
