What Is an Ounce?

An ounce (symbol: oz) is a mass unit in the British Imperial and U.S. customary measurement systems. The modern “avoirdupois” ounce is precisely 28.349523125 g, which is exactly one-sixteenth of an avoirdupois pound.

起源

オンス」の語源はラテン語である。 ウンシア, meaning “twelfth part.” In ancient Rome, a standard copper bar defining the pound and foot was split into twelve アンシアエ. Over time, regional variants of the ounce appeared (for example, Dutch ≈100 g, French ≈30.59 g, Spanish ≈28.75 g) until the international avoirdupois ounce was fixed in 1959.
