About This Conversion
US fluid ounces to milliliters converts American drink and container sizes into metric. One US fluid ounce is 29.5735 ml, so the familiar 12 oz can is 355 ml and a 16 oz "pint" glass is 473 ml.
Fluid ounces measure volume, never weight, and the two only line up for water. A 12 oz bag of coffee is 340 g by mass and has nothing to do with 355 ml; reading a solid product weight as a fluid volume is a common and expensive mistake in recipe scaling.
