Ounce

Definition: An ounce is a unit of mass in the imperial and US customary systems, equal to 1/16 of a pound, or 28.3495 grams.

History/origin: The name derives from the Latin "uncia", the same root as "inch" — historically a twelfth part of a larger whole.

Current use: The (avoirdupois) ounce is used for food packaging and postal weight in the US and UK. Precious metals use a different unit, the troy ounce, which shouldn't be confused with this one.

Gram

Definition: A gram is a metric unit of mass equal to 1/1000 of a kilogram.

History/origin: The gram was originally defined in 1795 as the mass of one cubic centimeter of water at its melting point.

Current use: The gram is used worldwide for cooking ingredients, small object weights, and nutritional labeling.
