Grains (gr)

Definition

A grain (gr) is one of the oldest units of mass, equal to approximately 64.799 milligrams or 1/7000 of a pound avoirdupois.

History

The grain is historically based on the weight of a single cereal grain (wheat or barley). It has been used since ancient civilizations and was the basis for many historical weight systems including the troy and apothecaries' systems.

Grains are used in ammunition and firearms (bullet and powder charge weights), archery (arrow weights), and some pharmaceutical compounding. The gold and jewelry industries use troy grains.

Grams (g)

Definition

A gram (g) is a metric unit of mass equal to one thousandth of a kilogram. It was originally defined as the mass of one cubic centimeter of water at 4°C.

History

The gram was introduced in 1795 as the base unit of mass in the original metric system. Though the kilogram later replaced it as the SI base unit, the gram remains the most commonly used unit for everyday small-scale measurements.

Current use

Grams are used worldwide for food labeling, cooking recipes, postal weighing, jewelry and gemstone measurement, and small-scale scientific work. Nutritional information on food packaging is universally expressed in grams.
