How to convert US fluid ounces to liters
US customary, imperial, and metric kitchen measures can have different sizes despite similar names. Use the system printed on your recipe or container.
Use x for the value in US fl oz, b for the intermediate value in L, and y for the result in L.
L = US fl oz × 0.0295735295625
Worked examples
10 US fl oz ≈ 0.295735295625 L
Step 1: (10 × 0.0295735295625) ≈ 0.295735295625 L.
Step 2: 0.295735295625 ÷ 1 ≈ 0.295735295625 L.20 US fl oz ≈ 0.59147059125 L
Step 1: (20 × 0.0295735295625) ≈ 0.59147059125 L.
Step 2: 0.59147059125 ÷ 1 ≈ 0.59147059125 L.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About US fluid ounces
A US fluid ounce is one 128th of a US liquid gallon. It measures volume and is different from an imperial fluid ounce or an ounce of mass.

Definitions and sources
Check which gallon, cup, or ounce you mean
A US liquid gallon contains 3.785411784 liters; an imperial gallon contains 4.54609 liters. This calculator labels both explicitly and does not substitute one for the other.
Our US customary cup is 236.5882365 mL. A recipe may instead use a 250 mL metric cup or a 240 mL cup. Fluid ounces measure volume, while ounces in the Weight category measure mass.
For a tank or room, calculate the volume using dimensions in the same length unit before converting its cubic units. Changing only one side’s unit will give an incorrect volume.
Check the cup or fluid-ounce convention before using a converted volume in recipe calculations.
