Common Volume Conversions

Metric and US Volume Units

Metric volume units commonly include milliliters, liters, cubic centimeters, and cubic meters. Milliliters and liters are widely used for drinks, food, medicine, and household containers, while cubic meters are used for much larger volumes.

US customary volume units commonly include fluid ounces, cups, pints, quarts, and gallons. These units are often used in recipes, beverages, fuel, and everyday household measurements in the United States.

Why Use a Volume Conversion Tool?

A volume calculator can help when following recipes, comparing container sizes, reading product labels, checking fuel capacity, converting drink measurements, or working with cubic measurements in construction and storage.

The capacity visualizer also gives approximate comparisons with familiar containers. These examples are not exact for every product, but they can make an unfamiliar volume easier to understand.
