Formula
liters = fluid ounces × 0.0295735
Volume conversions use US customary measure (the cup, fluid ounce, and gallon are US definitions, not imperial). 1 US cup = 236.588 mL, 1 US gallon = 3.785411784 L.
About Fluid ounces and Liters
Fluid ounces (fl oz): 1/128 of a US gallon, or 29.5735 mL; the UK imperial fluid ounce is slightly different at 28.4131 mL, a remnant of pre-metric British measurement. Common uses: US beverage container sizes (a 12-oz soda can), US liquid recipe measurements, and UK pub measures for spirits (where a 'single' is 25 or 35 mL but historically tracked from imperial fl oz).
Liters (L): One cubic decimeter, or 1,000 cubic centimeters; one liter of water at standard conditions weighs almost exactly one kilogram, a coincidence that made the unit popular for everyday volume measurement. Common uses: Beverage container sizes, fuel (especially outside the US, where fuel is sold by the liter), engine displacements, and large-volume cooking and chemistry.
How the conversion works
Volume conversions use US customary measure (the cup, fluid ounce, and gallon are US definitions, not imperial). 1 US cup = 236.588 mL, 1 US gallon = 3.785411784 L.
The exact relationship is liters = fluid ounces × 0.0295735, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
When this conversion matters
Converting between fluid ounces and liters comes up wherever volume measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
