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.
Current use
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.
Kilograms (kg)
Definition
A kilogram (kg) is the SI base unit of mass, equal to 1,000 grams. Since 2019, it is defined by the Planck constant rather than a physical artifact.
History
The kilogram was established in 1795 during the French Revolution as the mass of one liter of water. From 1889 to 2019, it was defined by the International Prototype of the Kilogram (a platinum-iridium cylinder in Paris). The 2019 redefinition linked it to the Planck constant for improved precision.
Current use
Kilograms are the universal standard for body weight, grocery products, luggage allowances, industrial materials, and scientific measurements. It is the base unit of mass in all scientific and most commercial contexts worldwide.
