Conversion
Volume converter
Convert any volume unit (metric or US or UK) to every other unit at once. Pick from milliliters, liters, cubic meters, US/UK gallons, quarts, pints, cups, fluid ounces, tablespoons, and teaspoons.
Formula
Volume is the most fragmented unit system because of cooking — US recipes use cups and tablespoons, UK recipes use ml or imperial gallons, scientific contexts use liters and m³. This converter handles all the common cases with exact factors.
Warning: US and UK gallons are different. 1 US gallon = 3.78541 L, 1 UK (imperial) gallon = 4.54609 L. Recipes labeled 'gallon' usually mean US in American cookbooks and UK in British ones. Cups also differ: US = 236.588 ml, UK = 284.131 ml, metric = 250 ml exactly (this calculator uses US cups).
Results are shown to 8 significant figures and switch to scientific notation for very large or very small values.
Examples
- 011 US gallon in liters→ 1 × 3.78541 = 3.78541 L
- 02500 ml in US cups→ 500 × 0.001 ÷ 0.236588 ≈ 2.1134 cups
- 031 US tablespoon in ml→ 1 × 14.7868 = 14.79 ml
- 041 m³ in US gallons→ 1 × 1000 ÷ 3.78541 ≈ 264.17 gal
