Convert volume measurements between metric, US customary, Imperial, and cubic units. Enter a value, choose the units, and see the converted result along with equivalent measurements in other supported units.

Whether you are measuring liquid for a recipe, checking container capacity, or working with a volume in cubic units, this volume converter makes it easier to compare measurements from different systems.

The converter supports metric, US customary, Imperial, and cubic measurements.

Metric units

Cubic meter (m³): A metric unit commonly used for larger volumes, such as room capacity or water storage.

Liter (L): A common unit for liquids and container capacity.

Milliliter (mL): One-thousandth of a liter, often used for smaller liquid quantities.

US customary units

US gallon (US gal): A US customary unit used for larger liquid quantities.

US quart (US qt): One-quarter of a US gallon.

US pint (US pt): One-eighth of a US gallon.

US cup (US cup): A common cooking measure. This converter uses the US customary cup definition.

US fluid ounce (US fl oz): A unit for smaller liquid quantities.

Tablespoon (US tbsp): A customary cooking measure.

Teaspoon (US tsp): A smaller customary cooking measure.

Imperial units

Imperial gallon (Imp gal): A British Imperial unit of liquid volume.

Imperial pint (Imp pt): One-eighth of an Imperial gallon.

Imperial fluid ounce (Imp fl oz): An Imperial unit smaller than an Imperial pint.

Cubic units

Cubic foot (ft³): Used for measuring spaces, storage capacity, and larger objects.

Cubic inch (in³): Often used for smaller spaces and product dimensions.

US customary and Imperial units share some names, but their volumes are different. A US gallon is not the same size as an Imperial gallon, and the same distinction applies to pints and fluid ounces.

For example:

1 US gallon = approximately 3.785 liters.

1 Imperial gallon = approximately 4.546 liters.

1 US pint = approximately 473.176 milliliters.

1 Imperial pint = approximately 568.261 milliliters.

Always check which measurement system a recipe, product specification, or instruction uses before converting.

Cup and spoon measurements can also vary between countries and recipes. The cup, tablespoon, and teaspoon values in this converter use US customary definitions; they should not be assumed to match every country's cooking measures.

Here are a few examples using clearly specified measurement systems:

These values are rounded for readability. The converter can display more decimal places when you increase the precision setting.

Volume conversions are useful in everyday tasks and technical work:

Cooking: Convert liquid quantities between liters, milliliters, US cups, tablespoons, and teaspoons.

Storage and containers: Compare the capacity of tanks, boxes, and other containers.

Home improvement: Convert cubic feet or cubic inches into liters or other units.

Product specifications: Understand volume measurements when products use different measurement systems.

Science and education: Work with metric and cubic units in calculations and exercises.

The correct unit matters as much as the numerical result. If a recipe specifies US cups, do not automatically treat them as an unspecified international cup. If a product lists an Imperial gallon, select the Imperial unit rather than the US gallon.

The precision setting controls how many decimal places appear in the result. A shorter result is often easier to read, while additional decimal places can help with detailed calculations. Displayed precision affects rounding in the result, not the underlying conversion factors.
