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

Where Grains are Used

Grains are used in different countries and regions for different applications and purposes. Here are some examples of where grains are used:

• In most countries that use the SI system, grains are not used for measuring weight, but only for measuring small masses, such as bullets, arrows, and seeds.
• In the United States, grains are sometimes used for measuring small masses, such as bullets, arrows, and seeds.
• In Canada, Australia and New Zealand, grains are sometimes used for measuring small masses, such as bullets, arrows, and seeds.
• In the United Kingdom, grains are sometimes used for measuring small masses, such as bullets, arrows, and seeds.
• In India, grains are sometimes used for measuring small masses, such as bullets, arrows, and seeds.

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.

Example Conversions of Grains to Other Units

Here are some examples of conversions of grains to other units of weight:

• 1 gr = 0.0023 oz
• 1 gr = 0.0001 lb
• 1 gr = 0.00000007 ton
• 1 gr = 0.000065 kg
• 1 gr = 0.0648 g
• 1 gr = 64.79891 mg
• 1 gr = 0.0042 oz t
• 1 gr = 0.0417 dwt

Kilograms: A Unit of Weight

Definition of the Kilogram

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.

Where Kilograms are Used

The kilogram is a unit of weight that is widely used to measure the weight of objects and substances such as food, clothes, animals, metals and chemicals. For example, an adult human body has an average weight of about 62 kg.

The kilogram is also used to measure the weight of some physical quantities such as force, pressure and torque. For example, one newton (N) is equal to one kilogram times one meter per second squared (kg x m/s²).

Example Conversions of Kilograms to Other Units

Here are some examples of how to convert kilograms to other units of weight using the conversion factors given above:

• 2 kg = 2 x 1000 g = 2000 g
• 3 kg = 3 x 2.2046226218 lb = 6.6138678654 lb
• 4 kg = 4 x 35.27396195 oz = 141.0958478 oz
• 5 kg = 5 x 0.001 t = 0.005 t
• 6 kg = 6 x 0.1574730444 st = 0.9448382664 st
