Volume Converter

Our Volume Converter is a comprehensive tool that helps you convert between different units of volume: liters (L), gallons (gal), cups, and milliliters (mL). Whether you’re following recipes from different countries, measuring liquids for various purposes, or working with international standards, this calculator makes volume conversion simple and accurate.

Understanding Volume Units

Metric System

Liters (L)

The liter is the most commonly used unit of volume in the metric system. It’s defined as the volume of a cube that is 10 centimeters on each side. The metric system is used worldwide in science, industry, and everyday life in most countries.

Milliliters (mL)

The milliliter is a smaller unit of volume, equal to 1/1000 of a liter. It’s commonly used for precise measurements in cooking, medicine, and laboratory work.

US Customary System

Gallons (gal)

The gallon is the largest commonly used unit of volume in the US customary system. It’s widely used in the United States for measuring large quantities of liquids, particularly fuel and milk.

Cups (cup)

The cup is a smaller unit of volume commonly used in cooking and baking in the United States. One US cup is equal to 1/16 of a US gallon.
