What is a Volume Converter?

A volume converter is a tool that converts measurements of volume (the amount of space occupied by a substance) from one unit to another. Whether you need to convert liters to gallons, cups to milliliters, or tablespoons to teaspoons, a volume converter makes these calculations instant and accurate.

Volume conversions are essential in many fields including cooking, baking, chemistry, medicine, engineering, and everyday life. Different countries and industries use different measurement systems (metric vs imperial), making conversions a common necessity.

Our volume converter supports 11 different units including metric units (liters, milliliters, cubic meters) and US/Imperial units (gallons, quarts, pints, cups, fluid ounces, tablespoons, teaspoons), handling everything from tiny measurements to large volumes.

How it Works

Our volume converter uses precise conversion factors to accurately transform values between different volume units:

  • Select Units: Choose the source unit and target unit from the dropdowns
  • Enter Value: Input the volume measurement you want to convert
  • Instant Results: The conversion is calculated automatically in real-time
  • Swap Units: Click the swap button to reverse the conversion direction

The converter works by first converting to a base unit (liters), then converting to the target unit. All conversions use standard, internationally recognized conversion factors for maximum accuracy.

Conversion Examples

Gallons to Liters

1 US gallon = 3.78541 liters

Example: A 10-gallon tank holds approximately 37.85 liters. A 5-gallon bucket holds approximately 18.93 liters.

Cups to Milliliters

1 US cup = 236.588 milliliters

Example: 2 cups of water is approximately 473 milliliters. A standard coffee cup (8 fl oz) is approximately 237 milliliters.

Tablespoons to Teaspoons

1 tablespoon = 3 teaspoons

Example: 2 tablespoons equals 6 teaspoons. This is a common conversion in cooking and baking recipes.

US vs Imperial Gallons

1 US gallon = 3.78541 L, 1 Imperial gallon = 4.54609 L

Example: A 20-gallon US tank holds 75.7 liters, while a 20-gallon Imperial tank holds 90.9 liters. Always check which gallon system is being used!

Frequently Asked Questions

What's the difference between US and Imperial gallons?

A US gallon is approximately 3.785 liters, while an Imperial gallon (used in the UK) is approximately 4.546 liters. The Imperial gallon is about 20% larger than the US gallon. Our converter includes both, so make sure you select the correct one for your needs.

How many cups are in a gallon?

There are 16 US cups in a US gallon. This is a standard conversion: 1 US gallon = 4 quarts = 8 pints = 16 cups = 128 fluid ounces.

Are fluid ounces and weight ounces the same?

No! Fluid ounces measure volume, while weight ounces measure mass. One fluid ounce of water weighs approximately one ounce, but this doesn't hold true for other substances. Always use fluid ounces (fl oz) for volume conversions.

Is my data stored or tracked?

No. All conversions happen entirely in your browser. We don't store, log, or transmit any values you enter. Your calculations are completely private.
