Facts about Grain
Basic facts: A grain is an archaic unit of measurement of mass. In the avoirdupois, troy weight, and apothecaries’ system it is equivalent to precisely 64.79891 milligrams. Nominally it is based on the mass of a single ideal seed of a cereal.
This unit of measure was the legal foundation of traditional English weight systems and is the only unit that is equivalent throughout the avoirdupois, troy, and apothecaries’ systems of mass. The grain was based on the weight of a single grain of barley, assumed to be equivalent to 1+1/3 grains of wheat.
History: On the 1st of July 1959, since the implementation of the international yard and pound agreement of the grain or troy grain, which symbol is [gr], the measure has been defined in terms of units of mass in the International System of Units as exactly 64.79891 milligrams. One gram is therefore around 15.43236 grains.
Use: The grain is generally used to measure the mass of propellants and bullets. The grain is the standard unit used to weigh arrows in archery. In the US the hardness of water is often measured in grains per US gallon [gpg] of equivalents to calcium carbonate.
Facts about Milligram
Basic facts: A milligram is a unit of weight and mass that is based on the kilogram, which is the International System of Units (SI) base unit of mass. It is equivalent to 1/1,000,000 kilograms or 1/1,000 grams.
History: As already mentioned, the milligram is based on the SI unit of weight and mass, the kilogram. It uses the “milli”, SI prefix as a SI unit, to denote that it is a submultiple of the base unit. The prefix – “milli” indicates a submultiple with respect to the gram, the kilogram.
Use: The milligram is widely used in many applications as a submultiple of an SI base unit, from widespread use in scientific labs, among other areas, to everyday use to measure the weight or mass of substances, foods, etc.
