Volume Converter

Volume measurement is critical in cooking, chemistry, medicine, engineering, and everyday tasks. Two major systems are in use: the metric system (liters, milliliters, cubic meters) and the imperial/US customary system (gallons, quarts, pints, cups, fluid ounces).

The liter (L) is the standard metric unit for everyday volume. 1 L = 1,000 mL = 1 cubic decimeter = 0.001 m³. The US gallon is 3.785 L, while the UK (imperial) gallon is 4.546 L — they are not the same, which causes confusion in fuel economy and recipe conversions.

Cooking uses special measurements: in the US, 1 cup = 8 fl oz = 236.59 mL, 1 tablespoon = 14.79 mL, 1 teaspoon = 4.93 mL. These are widely used in American recipes but differ from UK and Australian conventions. This tool covers all common volume units for both culinary and scientific use.

Cubic units (m³, cm³, ft³, in³) are used in engineering and construction. 1 m³ = 1,000 L, 1 cm³ = 1 mL. This equivalence is exact by definition, making metric conversions especially clean.
