oz
Sixteen per pound
Oz is an abbreviation for ounce, a unit of weight equal to one-sixteenth of a pound, or about 28 grams.
It appears on food packaging, in recipes, and wherever quantities are measured: Add 4 oz of butter.
Fluid ounces measure volume rather than weight: an 8 oz glass of water.
The abbreviation comes from the Italian word onza. (Capitalized Oz is the fictional land.)
