Volume Converter: Gallons, Liters, Cups & More

Volume conversion is a daily necessity in many fields, from culinary arts to chemical engineering. Whether you're cooking a recipe from another country, calculating the capacity of a fuel tank, or working on a science project, our Volume Converter handles everything from tiny kitchen measurements like teaspoons to large industrial units like cubic meters.

Choose Source Unit: Select the unit you currently have (e.g., Gallons).
Choose Target Unit: Select the unit you need (e.g., Liters).
Get Instant Results: The conversion appears immediately in the second box.

Kitchen & Industrial Units Explained

Liter (L): The metric base unit for volume. Used worldwide for beverages, fuel, and scientific measurements. 1 Liter is equivalent to 1,000 Milliliters.
Gallon (US): A customary unit in the United States used primarily for liquid capacity (like gasoline or milk). 1 US Gallon is approximately 3.785 Liters. Note: The UK Imperial Gallon is different (approx 4.54 Liters).
Cubic Meter (m³): The SI unit for volume, used for large-scale measurements in engineering, shipping, and construction (e.g., concrete or water usage). 1 Cubic Meter equals 1,000 Liters.
Fluid Ounce (fl oz): A common unit in US food labeling and recipes. 1 US Cup contains 8 Fluid Ounces.
Cup, Pint, Quart: Standard US customary units for cooking. 2 Cups = 1 Pint; 2 Pints = 1 Quart; 4 Quarts = 1 Gallon.

Why Accuracy Matters

Culinary Success: Baking is a science. A slight error in converting liquid ingredients (like oil or milk) can ruin the texture of a cake. Using precise conversions ensures your dish turns out perfectly, regardless of the recipe's origin.

Fuel & Efficiency: For travelers and logistics managers, converting between Gallons and Liters is essential for calculating fuel economy and costs across different countries.

Science & Medicine: Precise volume measurements (Milliliters, Microliters) are non-negotiable in laboratory settings and medication dosing.
