Ounces (oz)
Definition
An ounce (oz) is an imperial unit of mass equal to 1/16 of a pound or approximately 28.3495 grams. This refers to the avoirdupois ounce.
History
The ounce derives from the Latin 'uncia' meaning one-twelfth (of a Roman pound). The avoirdupois ounce (28.35 g) was standardized in medieval England and differs from the troy ounce (31.10 g) used for precious metals.
Current use
Ounces are widely used in the United States for food packaging, cooking recipes, postal rates, and product weights. They are also used informally in the UK for some food items.
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.
