# Common Units of Volume Measurement

Volume is how much three-dimensional space a substance (solid, liquid, gas, or plasma) or shape occupies or contains, often quantified numerically using the SI derived unit, the cubic metre. The volume of a container is generally understood to be the capacity of the container, i. e. the amount of fluid (gas or liquid) that the container could hold, rather than the amount of space the container itself displaces.

## Here are some common units of volume measurement:

### Wine barrels

Wine barrels, especially those made of oak, have long been used as containers in which wine is aged. Aging in oak typically imparts desirable vanilla, butter and spice flavors to wine. The size of the barrel plays a large role in determining the effects of oak on the wine by dictating the ratio of surface area to volume of wine with smaller containers having a larger impact.

### Barrel

Barrel is one of several units of volume, with dry barrels, fluid barrels (UK beer barrel, U.S. beer barrel), oil barrel, etc. The volume of some barrel units is double others, with various volumes in the range of about 100–200 litres (22–44 imp gal; 26–53 US gal).

### Liter

Liter or litre is a unit of volume equal to 1/1,000 cubic metre or 1 cubic decimetre (dm3).

### Centiliter

Centiliter is a common metric unit of volume. It is equal to 10 cubic centimeters. In the kitchen, a centiliter is roughly equal to 2 U.S. teaspoons (or 0.704 British tablespoonful).

### Deciliter

Deciliter is a common metric unit of volume. It is equal to 0.1 liter or 100 cubic centimeters.

### Dekaliter

Dekaliter is a metric unit of volume. It is equal to 10 liters.

### Kiloliter

Kiloliter is a metric unit of volume. Kiloliter is identical to the cubic meter. It is equal to 35.3147 cubic feet, or 1000 liters.

### Hectoliter

Hectoliter is a common metric unit of volume. It is equal to 100 liters, 0.1 cubic meter, 26.417 U.S. liquid gallons, 21.999 British imperial gallons, or 3.5315 cubic feet.

### Megaliter

Megaliter is a metric unit of volume. It is equal to 1000 cubic meters or 1000000 liters.

### Microliter

Microliter is a metric unit of volume used in chemistry and medicine to measure very small quantities of liquid. It is equal to 0.001 milliliter or 1 cubic millimeter. It is also called lambda.

### Milliliter

Milliliter is a very common metric unit of volume. It is equal to 0.001 liter, exactly one cubic centimeter.

### Cubic centimeter

Cubic centimetre (or cubic centimeter in US English) (symbol cm3 — the abbreviations cc and ccm, though widely used, are deprecated) is a commonly used unit of volume extending the derived SI-unit cubic metre, and corresponds to the volume of a cube measuring 1 cm × 1 cm × 1 cm. One cubic centimetre corresponds to a volume of 1⁄1000000 of a cubic metre, or 1⁄1000 of a litre, or one millilitre; thus, 1 cm3 ≡ 1 mL.

Cubic foot is an Imperial and US customary (non-metric) unit of volume, used in the United States and the United Kingdom. It is defined as the volume of a cube with sides of one foot (0.3048 m) in length.

### Cubic inch

Cubic inch is a unit of measurement for volume in the Imperial units and United States customary units systems. It is the volume of a cube with each of its 3 sides being one inch long.

### Cubic kilometer

Cubic kilometer is a unit of volume. It is equal to 1000000000000 liters.

### Cubic meter

Cubic meter or cubic metre (symbol: m3) is the SI derived unit of volume. It is the volume of a cube with edges one metre in length. An alternative name, which allowed a different usage with metric prefixes, was the stère. Another alternative name, not widely used any more, is the kilolitre.

### Cubic micrometer

Cubic micrometer is a unit of volume. It is equal to 0.000000000000001 liter.

### Cubic mile

Cubic mile is an imperial / U.S. customary (non-SI non-metric) unit of volume, used in the United States, Canada, and the United Kingdom. It is defined as the volume of a cube with sides of 1 mile (5280 feet, 1760 yards, ≈1.609 kilometre) in length.

### Cubic millimeter

Cubic millimeter is a SI unit of volume. It is equal to 0.000001 liter.

### Cubic yard

Cubic yard is an Imperial / U.S. customary (non-SI non-metric) unit of volume, used in the United States, Canada, and the UK. It is defined as the volume of a cube with sides of 1 yard (3 feet, 36 inches, 0.9144 metres) in length.

### Cup

Cup is a customary unit of measurement mainly used in North America for volume, used in cooking to measure liquids (fluid measurement) and bulk foods such as granulated sugar (dry measurement). This measure is usually used as an informal unit in cooking recipes where precision is rarely required, rather than as a measure for the sale of foodstuffs.

In Canada, a cup is equal to 8 Imperial fluid ounces (or 0.2273045 liter).

### Metric cup

Metric cup is an informal metric unit of volume. It is equal to 0.25 liter, commonly used in recipes in Australia.

### U.S. cup

US cup is a traditional unit of volume used in recipes in the United States. It is equal to 1/2 liquid pint, or 8 fluid ounces or 0.2365882375 liter.

### Gallon

Gallon is a measure of volume approximately equal to four liters. Historically it has had many different definitions, but there are three definitions in current use. In United States customary units there are the liquid (≈ 3.79 L) and the lesser used dry (≈ 4.4 L) gallons. There is also the imperial gallon (≈ 4.55 L) which is in unofficial use within the United Kingdom and Ireland and is in semi-official use within Canada.

### U.K. gallon
