Definition of Volume

Volume is a fundamental measurement that quantifies the amount of space occupied by a three-dimensional object or substance.

How to convert volume units

Type a value into any field, and every other unit is calculated at once. A volume unit is a length unit cubed, so its factor is cubed too: a meter is 100 cm, so a cubic meter is 100 * 100 * 100 = 1,000,000 cm³, and a liter is 1,000 cm³.

For example, a 20 US gallon fish tank:

1. In liters: multiply by 3.78541.

   20 * 3.78541 = 75.71 L

2. In UK gallons: the UK gallon is about 20% larger.

   20 US gal = 16.65 UK gal

Common conversions

The US barrel here is the 31.5-gallon barrel for liquids. An oil barrel is 42 US gallons, 158.99 L, and is in the Flow Converter as a rate.

Units of Volume

Metric Units

• Liter (l) - A liter is the base unit of volume in the metric system, denoting the volume occupied by one cubic decimeter. It is equivalent to 1,000 milliliters, 10 deciliters, or 0.001 cubic meters.

• Deciliter (dl) - A deciliter is equal to 1/10 of a liter or 100 milliliters.

• Milliliter (ml) - A milliliter is equivalent to 1/1000 of a liter or one cubic centimeter.

• Cubic Meter (m³) - A cubic meter is the SI unit for volume, representing the volume occupied by a cube with edges measuring one meter. It is equivalent to 1,000 liters.

• Cubic Centimeter (cm³) - A cubic centimeter is equivalent to one milliliter or 1/1000 of a liter.

Imperial Units

• Cubic Yard (yd³) - A cubic yard is a unit of volume in the imperial system, representing the volume occupied by a cube with edges measuring one yard. It is equivalent to 27 cubic feet.

• Cubic Foot (ft³) - A cubic foot is equal to the volume occupied by a cube with edges measuring one foot. It is equivalent to 1,728 cubic inches.

• Cubic Inch (in³) - A cubic inch is the volume occupied by a cube with edges measuring one inch. It is equivalent to 0.000579 cubic feet or 0.0000214335 cubic yards.

• US Barrel (bbl) - The US barrel is a unit of volume commonly used for measuring the capacity of oil barrels. It is equivalent to 31.5 US gallons or 119.24 liters.

• UK Barrel (bbl) - The UK barrel is a unit of volume primarily used for measuring the capacity of beer and ale barrels. It is equivalent to 36 UK gallons, or 163.66 liters.

• US Gallon (gal) - The US gallon is a widely used unit for liquid volume in the United States. It is equivalent to 3.78541 liters.

• UK Gallon (gal) - The UK gallon is commonly used in the United Kingdom and differs slightly from the US gallon. It is equivalent to 4.54609 liters.

• US Quart (qt) - The US quart is 1/4 of a US gallon, commonly used in cooking and the beverage industry.

• UK Quart (qt) - The UK quart is a unit of volume used in the UK, representing 1/4 of a UK gallon.

• US Fluid Ounce (fl oz) - The US fluid ounce measures volume in liquid substances, commonly used in recipes and beverages. It is equivalent to 1/128 of a US gallon, or 29.5735 milliliters.

• UK Fluid Ounce (fl oz) - The UK fluid ounce is a unit of volume used in the UK for measuring liquid substances. It is equivalent to 1/160 of a UK gallon, or 28.4131 milliliters.

Frequently asked questions

How many liters are in a cubic meter?

1,000. A cubic meter is a cube 1 m on each side, and a liter a cube 10 cm on each side, so 10 × 10 × 10 liters fit in it.

Are there cooking measures too?

Cups, tablespoons and teaspoons, in their US, UK and metric versions, are in the Cooking Converter.
