Volume Converter

Convert liters, gallons (US & UK), cups, cubic feet, barrels and more.

The Volume Converter is the kitchen-and-industry workhorse: liters and milliliters, US and UK gallons (which differ by about 20%!), fluid ounces, cups, teaspoons and tablespoons, plus cubic meters, cubic feet, cubic inches and oil barrels.

Volume units are a minefield of near-identities: a US gallon is 3.785 L while a UK gallon is 4.546 L; a US fluid ounce is 29.57 mL while the imperial one is 28.41 mL; even 'a cup' differs (240 mL US). Recipes, fuel economy, engine sizes, shipping, brewing and cocktails all mix these systems — and guessing wrong scales a batch by 20% or more.

This converter keeps US and UK units clearly labelled and separate, gives exact conversions from each unit's definition in liters, and runs entirely in your browser.

Result

1 L = 0.264172052358 gal (US)

1 L = 0.264172052358 gal (US)

1 gal (US) = 3.785411784 L

Frequently asked questions

How many liters are in a gallon?

A US gallon is exactly 3.785411784 L. A UK (imperial) gallon is exactly 4.54609 L. The two are not interchangeable — the UK gallon is about 20% larger — which is why this converter labels them separately.

How do I convert cups to milliliters?

A US cup is 240 mL (236.6 mL in strict US legal terms; the converter uses 236.588 mL). Multiply cups by 240 for a close kitchen figure. Metric recipes often measure everything in mL or grams instead, so a converter bridges the gap.

How many liters is a cubic foot?

Exactly 28.316846592 L — about 28.3 L. Cubic feet appear in fridges, freezers, shipping and lumber; liters appear everywhere else, so the conversion comes up constantly in appliance shopping.
