Ounce, unit of measure

The ounce (abbreviation: oz) is the name of a unit of mass in a number of different systems, including various systems of mass that formed part of English units, Imperial units, and United States customary units. Its size can vary from system to system. The most commonly used ounces used today are the international avoirdupois ounce and the international troy ounce. Historically, in different parts of the world, at different points in time, and for different applications, the ounce (or its translation) has referred to broadly similar but different standards of mass (or weight, before the distinction between weight and mass developed). Some countries have redefined their ounces to fit in with the metric system. The Dutch have redefined their ounce (in Dutch, ons) as 100 grams. This was adopted along with the introduction of the metric system and remains in informal usage.
