Guide
What is a volume conversion?
A volume conversion expresses the same liquid or general capacity in a different unit. This Converter uses liters as the common base and supports metric and US customary liquid measures.
Formula
Converted value = Input value × (Source unit to liters) ÷ (Target unit to liters). For example, 1 US gallon equals 3.785411784 liters and 1 liter equals 1,000 milliliters.
Worked example
To convert 1 US gallon to liters, multiply 1 by 3.785411784. The result is 3.785411784 liters.
Assumptions and limitations
The Converter uses US liquid definitions for gallons, quarts, pints, cups, and fluid ounces. Values must be zero or greater. It does not model dry volume measures or imperial UK gallons.
Common questions
Are US and UK gallons the same?
No. This Converter uses the US liquid gallon of 3.785411784 liters. Which kitchen units are included? Cups, tablespoons, teaspoons, and fluid ounces use US customary liquid definitions. Can I convert cubic measurements? No. This Converter handles liquid-style volume units only.
Methodology
Each unit stores a fixed multiplier to liters. The Converter applies exact decimal arithmetic and rounds only for display.
