Fluid Ounce (US) to Liter (US fl oz to L)
Result
0.02957352956 Liter
Formula
L = US fl oz × 0.02957352956
1 US fl oz = 0.02957352956 L, and 1 L = 33.8140227 US fl oz.
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 US fl oz × 0.02957352956 = 0.02957353 L
- 10 US fl oz × 0.02957352956 = 0.2957353 L
- 100 US fl oz × 0.02957352956 = 2.957353 L
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.
