What this converter does
The Liquid & Volume Converter changes one entered amount into several common units at the same time. It supports US teaspoons, US tablespoons, US fluid ounces, US cups, US pints, US quarts, US gallons, milliliters, and liters.
How liquid and volume conversion works
Each unit is converted through a shared base unit: milliliters. For example, US gallons convert to milliliters using the exact relationship 1 US gallon = 3,785.411784 milliliters. The result is then converted from milliliters into each target unit.
This page uses US liquid measurements for teaspoons, tablespoons, fluid ounces, cups, pints, quarts, and gallons. US and Imperial UK volume units differ, so check the measurement system if a recipe or container label comes from outside the United States.
Worked example
If you enter 5 US gallons, the converter first turns that amount into 18,927.05892 milliliters. From there it can show 18.92705892 liters, 20 US quarts, 40 US pints, 80 US cups, and 640 US fluid ounces.
