- U. S. customary fluid ounce
- The U. S. customary fluid ounce is defined to be 1â„128 of a U. S. gallon. This volume of cool, pure water weighs about 1. 04 avoirdupois ounces (29. 5 g).
- U. S. food labelling fluid ounce
- U. S. regulation 21 CFR 101. 9(b)(5)(viii) also defines a fluid ounce as exactly 30 millilitres, but this is for use in nutrition labelling only. [5] This is not meant to concur with the customary US definition exactly but is a common source of confusion.
- Other useful conversions
Given the definitions above, we can calculate how many US fluid ounces are in one liter:
1/29. 5735295625 * 1000 = 33. 8140
There are thus about 34 fluid ounces in one liter.
