Liter to Fluid Ounce (US) (L to US fl oz)
Result
33.8140227 Fluid Ounce (US)
Formula
US fl oz = L × 33.8140227
1 L = 33.8140227 US fl oz, and 1 US fl oz = 0.02957352956 L.
The litre is exactly 1 dm³ (0.001 m³). The US gallon is defined as 231 cubic inches, which makes it exactly 3.785411784 L; quarts, pints, cups and fluid ounces are fixed fractions of it.
Worked examples
- 1 L × 33.8140227 = 33.814023 US fl oz
- 10 L × 33.8140227 = 338.14023 US fl oz
- 100 L × 33.8140227 = 3,381.4023 US fl oz
Common mistakes
- US and UK (imperial) measures share names but not sizes: the imperial gallon is 4.54609 L (20% larger), the imperial pint 568 mL and the imperial fluid ounce 28.41 mL.
- This converter uses US customary volumes. A US cup is 236.59 mL, a metric cup 250 mL, and US nutrition labels round a cup to 240 mL.
- US dry measures (dry pint, bushel) are a separate system and are not the same as liquid pints.
