About the ounce
The ounce comes from Latin "uncia" meaning one-twelfth. The avoirdupois ounce (1/16 of a pound) became the standard in trade, distinct from the troy ounce used for precious metals.
In everyday use the ounce appears in food packaging, cooking recipes, postal weight, and beverage servings. As a point of reference: a slice of bread weighs about 1 ounce.
