Volume & Liquid Conversion Guide

Volume conversions are essential in cooking, chemistry, fuel measurement and everyday life. Our volume converter handles both liquid volume (liters, gallons, fluid ounces, cups) and cubic volume (cubic meters, cubic feet, cubic inches).

One of the most important things to know about volume conversions is that the US gallon and the UK (imperial) gallon are different sizes. The US gallon equals 3.78541 liters, while the UK gallon equals 4.54609 liters. Similarly, a US fluid ounce (29.5735 mL) is slightly different from a UK fluid ounce (28.4131 mL). Our converter clearly distinguishes between US and UK units to avoid confusion.

Cooking Volume Conversions

In cooking, the most common conversions are between milliliters and fluid ounces, cups and milliliters, and tablespoons and teaspoons. One US cup equals 236.588 mL. One tablespoon equals 14.7868 mL. One teaspoon equals 4.92892 mL. These conversions are critical when following recipes from different countries, since American recipes use cups while European recipes typically use grams and milliliters.
