Liters to US Fluid Ounces

Convert any metric liquid volume into precise US fluid ounces using the exact international conversion factor—useful for mixology, nutrition labels, and scientific protocols.

Enter liters directly or divide milliliters by 1,000 before input (e.g., 750 mL → 0.75 L).

Follow applicable food labelling laws or laboratory protocols when reporting converted volumes. Some regulations require specifying both metric and US customary units.

Examples

  • 1.5 L sports bottle ⇒ 50.72 US fl oz
  • 0.75 L wine bottle ⇒ 25.36 US fl oz
  • 3.8 L (one US liquid gallon) ⇒ 128.00 US fl oz
  • 0.25 L recipe portion ⇒ 8.45 US fl oz

FAQ

Can I enter volumes in milliliters or cubic centimeters?

Yes. Convert to liters first by dividing by 1,000 (e.g., 355 mL soda can = 0.355 L) or 1,000,000 for cubic centimeters.

Why do US and Imperial fluid ounces differ?

The US customary system defines a gallon as exactly 231 cubic inches, while the Imperial gallon is 277.42 cubic inches. That base difference propagates to the fluid ounce size.

Is the conversion factor rounded?

The calculator uses the exact defined factor. Any rounding you see is solely in the displayed output for readability.

Should I use this for dry ingredients?

Fluid ounces measure volume, not weight. For flour, sugar, or grains, convert using weight measures tailored to the ingredient's density.

Additional Information

  • Exact constant: 1 liter equals 33.8140227 US fluid ounces, derived from the international inch at 2.54 cm.
  • For Imperial (UK) fluid ounces, multiply liters by 35.195079 instead to match UK beverage labelling.
  • To convert the result back to liters, divide the US fluid ounces value by 33.8140227.
