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.

Fact about Pound

Basic facts:  A pound is a unit of mass used in the United States customary and imperial systems of measurement. Its symbol is [lb.]. The common pound used today is the international avoirdupois pound. It is defined as precisely 0.45359237 kilograms. One avoirdupois pound is equal to 16 (sixteen) avoirdupois ounces.

History: Prior to the international avoirdupois pound that is widely used today, numerous different definitions of the pound were used throughout history. The pound descended from the Roman libra. The avoirdupois system was commonly used in the 13th century. In 1959, it was updated to its current form. This system was based on a physical standardized pound that used a prototype weight. This prototype weight could be divided into a number that had three even divisors [8, 4, 2] i.e., 16 ounces.

Use: In the United States, the pound as a unit of weight is widely used, often for measuring body weight. Many versions of the pound existed in the past in the UK, and although the United Kingdom largely uses the International System of Units, pounds are still used within specific contexts, such as labeling of packaged foods [by law the metric values must also be displayed]. The United Kingdom also often uses both pounds and stones when defining body weight, where a stone is comprised of 14 (fourteen) pounds.
