About Fluid Ounces
A fluid ounce (fl oz) is a US customary volume unit equal to 1/8 of a cup or 1/128 of a gallon - approximately 29.574 mL. Despite sharing a name with the weight unit 'ounce', fluid ounces measure volume, not mass. In the US, beverages are universally labeled in fluid ounces: a standard can of soda is 12 fl oz, a standard wine pour is 5 fl oz, and a shot of spirits is 1.5 fl oz. Note that the UK imperial fluid ounce (28.413 mL) differs slightly from the US fluid ounce (29.574 mL) - a common source of confusion in international recipes and product comparisons.
