12ounce

12ounce, typically written as 12 oz or 12-ounce, is a unit of volume used in the United States to denote a standard beverage container size. It equals 12 US fluid ounces, which is approximately 355 milliliters. This measurement is part of the US customary system and is distinct from the ounce used for weight (avoirdupois ounce).

In common usage, 12 oz is a prevalent can or bottle size for beverages such as beer, soda, and energy drinks. It is frequently seen on product labels and advertising, and brands often stylize the shorthand without a space or with a hyphen (12oz or 12-oz). While 12 oz is a standard reference size, actual container capacities can vary by product or market, with other sizes such as 8 oz, 16 oz, and larger options also available.

Conversions and context: 1 cup equals 8 fluid ounces; 1 pint equals 16 fluid ounces; 1 quart equals 32 fluid ounces. Therefore, 12 fluid ounces is 0.75 pint or 0.375 quart. Because 12 ounces refer to volume, the corresponding mass depends on the liquid’s density; for example, 12 fl oz of water weighs about 355 grams (roughly 12.5 ounces avoirdupois).
