🧪 Free Volume Converter

What is this tool?

The Volume Converter is a free online tool for converting liquid and container volumes between metric and imperial units: milliliters (mL), liters (L), cubic meters (m³), US gallons, US quarts, and cups. Use it for cooking and baking, fuel and vehicle capacities, beverage and chemical measurements, and home projects. All conversions run locally in your browser — fast, free, and private.

How it works

The converter uses the liter as the base unit: 1 L = 1000 mL, 1 m³ = 1000 L, 1 US gallon = 3.785411784 L, 1 US quart = 0.946352946 L, and 1 US cup = 0.2365882365 L. Your input is converted to liters first, then to the target unit, so every combination converts exactly.

How to use

1. Enter the volume value you want to convert.
2. Select the input unit (mL, L, m³, gal, qt, or cup) from the first dropdown.
3. Select the target unit from the second dropdown and click Convert.
4. The converted volume is displayed instantly along with the conversion summary.
