Volume Converter
Convert between liters, gallons, cups, and more
Conversion Formula
For linear units: Target = Value × (From Ratio / To Ratio)
Volume conversions are linear. The formula is: Target Value = Source Value × (Source Unit Ratio / Target Unit Ratio). For example, to convert 1 liter to gallons: 1 × (1 / 3.7854) ≈ 0.264 gallons.
Volume conversion is used in cooking, chemistry, engineering, and everyday life. Whether you are scaling a recipe from milliliters to cups or measuring fuel in gallons, our converter handles it all.
All standard US customary and metric volume units are included: liters, milliliters, cubic meters, gallons, quarts, pints, cups, fluid ounces, tablespoons, and teaspoons.

Frequently Asked Questions
This converter uses US gallons (3.785 L). An Imperial gallon is 4.546 L. We focus on US customary units.
In US customary units, a fluid ounce is a unit of volume. A fluid ounce of water weighs about 1 ounce, but this varies by density.
There are exactly 1,000 milliliters (mL) in 1 liter (L). This is consistent across all metric volume measurements.
There are 4 cups in 1 US quart. Since 1 cup equals 8 fluid ounces and 1 quart equals 32 fluid ounces, 4 cups make 1 quart.
In US measurements, a dry quart (1.101 L) is slightly larger than a liquid quart (0.946 L). This converter uses liquid quarts for standard volume conversions.
1 cubic meter (m³) equals 1,000 liters. Simply multiply the cubic meter value by 1,000 to get liters. For example, 2.5 m³ = 2,500 L.
There are 16 tablespoons (tbsp) in 1 US cup. This is useful for cooking and baking when you need to scale recipes.
