What is a Ounce and a Microgram?
The ounce (oz) is a unit of mass used in the British imperial and United States customary systems of measurement. The most common type today is the international avoirdupois ounce, defined as exactly 1/16 of an avoirdupois pound, or approximately 28.35 grams.
A microgram is a unit of mass in the metric system equal to one millionth (1/1,000,000) of a gram, or one thousandth (1/1,000) of a milligram. It is often denoted by the symbol µg.
Note: The Ounce is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Microgram belongs to the metric (SI) system.
History of the Ounce and Microgram
The term "ounce" derives from the Roman "uncia", which was one-twelfth of the Roman pound. Its value varied throughout history and regions. The avoirdupois ounce became standardized in the English-speaking world for general trade.
The microgram is derived from the gram, a base unit in early metric systems defined in the late 18th century. The prefix "micro-" indicates a factor of 10⁻⁶.
