What is the Volume Converter?
Written and maintained by the BitConvert team · Feb 27, 2026
The BitConvert Volume Converter moves capacity values between metric and US customary units, covering milliliters, liters, and cubic meters alongside US gallons, fluid ounces, cups, pints, and quarts. It also lists the UK (imperial) gallon separately, because the two gallons are not the same size.
That distinction matters: a US gallon is 3.78541 liters while a UK gallon is 4.54609 liters, so recipes and fuel figures can be off by nearly 20 percent if you mix them up. Smaller kitchen units are handled too, with 1 liter equal to about 4.227 US cups. Enter a value, choose your source and target units, adjust the decimal precision, and read the result instantly in your browser, using the swap button to flip between the two units whenever you need the inverse.
