What the Volume Converter does
This tool converts between metric and US volume units for cooking, science, fuel, and shipping. It handles milliliters, liters, and cubic meters alongside teaspoons, tablespoons, fluid ounces, cups, pints, quarts, and gallons, so recipes that mix systems or fuel figures quoted in liters versus gallons are easy to reconcile.
How to use it
- Type the amount in the Value box.
- Pick your starting unit in the From row (for example L).
- Your value appears in every other unit instantly below, with nothing to click.
- Tap any unit (for example gal) to copy its value to your clipboard.
A note on cups and ounces
Cooking units differ by country. This converter uses US customary measures, where 1 cup is about 236.6 mL and 1 fluid ounce is about 29.6 mL, so it matches most US recipes. For UK or metric recipe cups, expect a small difference. The math runs locally in your browser, so your numbers are never uploaded.
