About this tool

Volume is the amount of space a substance occupies, and it is measured in a confusing mix of units that vary by country and by trade. This converter puts them side by side so you can move a single value across all of them at once. Type a number, choose the unit you have, and read the equivalent in every other unit instantly.

The trickiest part of volume is that a gallon is not a gallon everywhere. A US gallon is about 3.785 liters, while an imperial gallon used in the UK and much of the Commonwealth is about 4.546 liters. The same split runs through quarts, pints, cups, and fluid ounces, which is why recipes and fuel figures so often disagree. The system toggle here keeps those measures consistent so you never mix a US pint with an imperial one by accident.

Everything is calculated through a shared liter base, so metric units like milliliters and cubic meters line up cleanly with cubic feet and cubic inches used in shipping and construction. Zero and empty inputs simply clear the results rather than showing errors, and very large or very small numbers are formatted to stay readable.
