Cubic meter (1,000L)
The cubic metre (in British English and international spelling as used by the International Bureau of Weights and Measures) or cubic meter (in American English) is the SI derived unit of volume. Its SI symbol is m3. 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, still sometimes used for dry measure (for instance, in reference to wood). Another alternative name, no longer widely used, was the kilolitre.
-
Cubic Yard (764.5549L)
A cubic yard (symbol yd³) 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 meters) in length.
-
UK Barrel (163.6592L)
A barrel is one of several units of volume applied in various contexts; there are dry barrels, fluid barrels (such as the UK beer barrel and US beer barrel), oil barrels and so on. For historical reasons the volumes of some barrel units are roughly double the volumes of others; volumes in common usage range from about 100 to 200 litres (22 to 44 imp gal; 26 to 53 US gal). In many connections the term "drum" is used almost interchangeably with "barrel".
-
US Barrel (Oil) (158.9873L)
A barrel is one of several units of volume applied in various contexts; there are dry barrels, fluid barrels (such as the UK beer barrel and US beer barrel), oil barrels and so on. For historical reasons the volumes of some barrel units are roughly double the volumes of others; volumes in common usage range from about 100 to 200 litres (22 to 44 imp gal; 26 to 53 US gal). In many connections the term "drum" is used almost interchangeably with "barrel". In the worldwide oil industry, an oil barrel is defined as 42 US gallons, which is about 159 litres or 35 imperial gallons.
-
US Barrel (Liquid) (119.2405L)
A barrel is one of several units of volume applied in various contexts; there are dry barrels, fluid barrels (such as the UK beer barrel and US beer barrel), oil barrels and so on. For historical reasons the volumes of some barrel units are roughly double the volumes of others; volumes in common usage range from about 100 to 200 litres (22 to 44 imp gal; 26 to 53 US gal). In many connections the term "drum" is used almost interchangeably with "barrel". In the US most fluid barrels (apart from oil) are 31.5 US gallons (26 imp gal; 119 L) (half a hogshead), but a beer barrel is 31 US gallons (26 imp gal; 117 L). The size of beer kegs in the US is based loosely on fractions of the US beer barrel.
-
US Barrel (Dry) (115.6271L)
A barrel is one of several units of volume applied in various contexts; there are dry barrels, fluid barrels (such as the UK beer barrel and US beer barrel), oil barrels and so on. For historical reasons the volumes of some barrel units are roughly double the volumes of others; volumes in common usage range from about 100 to 200 litres (22 to 44 imp gal; 26 to 53 US gal). In many connections the term "drum" is used almost interchangeably with "barrel". Defined as length of stave 28 1⁄2 in (72 cm), diameter of head 17 1⁄8 in (43 cm), distance between heads 26 in (66 cm), circumference of bulge 64 in (1.6 m) outside measurement; representing as nearly as possible 7,056 cubic inches; and the thickness of staves not greater than 4⁄10 in (10 mm) ([Ø ≈ 20.37 in or 51.7 cm]). Any barrel that is 7,056 cubic inches is recognized as equivalent. This is exactly equal to 26.25 US dry gallons.
-
Cubic Foot (28.31685L)
The cubic foot (symbol ft³) is an imperial and US customary (non-metric) unit of volume, used in the United States, and partially in Canada, and the United Kingdom. It is defined as the volume of a cube with sides of one foot (0.3048 m) in length. Its volume is 28.3168 liters or about 1⁄35 of a cubic meter. At 60 °F (16 °C), a cubic foot of water weighs 62.36630 pounds (28.28888 kg).
-
UK Gallon (4.546090L)
The gallon is a unit of measurement for fluid capacity in both the US customary units and the British imperial systems of measurement. Three significantly different sizes are in current use: the imperial gallon defined as 4.54609 litres (4 imperial quarts or 8 imperial pints), which is used in the United Kingdom, Canada, and some Caribbean nations; the US gallon defined as 231 cubic inches (4 US liquid quarts or 8 US liquid pints) or about 3.785 L, which is used in the US and some Latin American and Caribbean countries; and the least-used US dry gallon defined as 1/8 US bushel (4.405 L).
-
US Gallon (Dry) (4.404884L)
This dry measure is one-eighth of a US Winchester bushel of 2150.42 cubic inches; it is therefore equal to exactly 268.8025 cubic inches or about 4.405 L. The US dry gallon is not used in commerce, and is not listed in the relevant statute, which jumps from the dry quart to the peck.
-
US Gallon (Liquid) (3.785412L)
The US gallon is legally defined as 231 cubic inches, which is exactly 3.785411784 litres. A US liquid gallon of water weighs about 8.34 pounds or 3.78 kilograms at 62 °F (17 °C), making it about 16.6% lighter than the imperial gallon. There are four quarts in a gallon, two pints in a quart and 16 US fluid ounces in a US pint, which makes the US fluid ounce equal to 1/128 of a US gallon. In order to overcome the effects of expansion and contraction with temperature when using a gallon to specify a quantity of material for purposes of trade, it is common to define the temperature at which the material will occupy the specified volume. For example, the volume of petroleum products and alcoholic beverages are both referenced to 60 °F (15.6 °C) in government regulations.
-
UK Quart (1.136523L)
The imperial quart, used for both liquid or dry capacity, is equal to one quarter of an imperial gallon, or exactly 1.1365225 liters.
-
US Quart (Dry) (1.101221L)
In the United States, the dry quart is equal to 1/4 of a US dry gallon, exactly 1.101220942715 liters.
-
Liter (1L)
The litre (SI spelling) or liter (American spelling) (symbols L or l, sometimes abbreviated ltr) is an SI accepted metric system unit of volume equal to 1 cubic decimetre (dm3), 1,000 cubic centimetres (cm3) or 1/1,000 cubic metre. A cubic decimetre (or litre) occupies a volume of 10 cm×10 cm×10 cm and is thus equal to one-thousandth of a cubic metre.
-
US Quart (Liquid) (0.9463530L)
In the United States, all traditional length and volume measures have been legally standardized for commerce by the international yard and pound agreement of 1959 using the definition of 1 yard being exactly equal to 0.9144 meter. From this definition is derived the metric equivalencies for inches, feet, and miles; as well as area measures; and measures of volume. The US liquid quart equals 57.75 cubic inches, which is exactly equal to 0.946352946 liters.
-
UK Pint (0.5682612L)
The pint (symbol pt sometimes abbreviated as "p") is a unit of volume or capacity in both the imperial and United States customary measurement systems. In both of those systems it is traditionally one-eighth of a gallon. The British imperial pint is about 20% larger than the American pint because the two systems are defined differently. Almost all other countries have standardized on the metric system, so the size of what may be called a pint varies depending on local custom.
-
US Pint (Dry) (0.5506105L)
The pint (symbol pt, sometimes abbreviated as "p") is a unit of volume or capacity in both the imperial and United States customary measurement systems. In both of those systems it is traditionally one-eighth of a gallon. The British imperial pint is about 20% larger than the American pint because the two systems are defined differently. Almost all other countries have standardized on the metric system, so the size of what may be called a pint varies depending on local custom. In the United States, the dry pint is one-eighth of a dry gallon.
-
US Pint (Liquid) (0.4731765L)
In the United States, the liquid pint is legally defined as one-eighth of a liquid gallon of precisely 231 cubic inches.
-
Metric Cup (0.25L)
The cup is a United States unit of volume, most commonly associated with cooking and serving sizes. It is traditionally equal to half a liquid pint in US customary units but is now separately defined in terms of the metric system at values between 1⁄5 and 1⁄4 of a liter. Because actual drinking cups may differ greatly from the size of this unit, standard measuring cups are usually used instead. Australia, Canada, New Zealand, and some other members of the Commonwealth of Nations—being former British colonies that have since metricated—employ a "metric cup" of 250 millilitres. Although derived from the metric system, it is not an SI unit.
-
US Cup (0.2365855L)
The cup is a United States unit of volume, most commonly associated with cooking and serving sizes. It is traditionally equal to half a liquid pint in US customary units but is now separately defined in terms of the metric system at values between 1⁄5 and 1⁄4 of a liter. Because actual drinking cups may differ greatly from the size of this unit, standard measuring cups are usually used instead.
-
Canadian Cup (0.2273045L)
The cup is a United States unit of volume, most commonly associated with cooking and serving sizes. It is traditionally equal to half a liquid pint in US customary units but is now separately defined in terms of the metric system at values between 1⁄5 and 1⁄4 of a liter. Because actual drinking cups may differ greatly from the size of this unit, standard measuring cups are usually used instead. Canada now usually employs the metric cup of 250 mL but its conventional cup was somewhat smaller than both American and imperial units.
-
Gill (UK) (0.1420653L)
The gill or teacup is a unit of measurement for volume equal to a quarter of a pint. It is no longer in common use, except in regard to the volume of alcoholic spirits measures. 1 imperial gill equals to 5 imperial fluid ounces, 1⁄32 imperial gallon, 1⁄4 imperial pint, ≈ 142 ml, ≈ 1.2 US gills
-
US Gill (0.1182941L)
The gill or teacup is a unit of measurement for volume equal to a quarter of a pint. It is no longer in common use, except in regard to the volume of alcoholic spirits measures. 1 US gill is equal to 4 US fl oz, 1⁄32 US gallon, 1⁄4 US pint, ≈ 118 ml, ≈ 5⁄6 imperial gills.
-
US Fluid Ounce (0.02957353L)
A fluid ounce (abbreviated fl oz, fl. oz. or oz. fl.) is a unit of volume (also called capacity) typically used for measuring liquids. Various definitions have been used throughout history, but only two are still in common use: the British Imperial and the United States customary fluid ounce. A US fluid ounce is 1⁄16 of a US fluid pint and 1⁄128 of a US liquid gallon or approximately 29.57 ml, making it about 4% larger than the imperial fluid ounce. The fluid ounce is distinct from the ounce as a unit of weight or mass, although it is sometimes referred to simply as an "ounce" where context makes the meaning clear, such as ounces in a bottle.
-
UK Fluid Ounce (0.02841306L)
A fluid ounce (abbreviated fl oz, fl. oz. or oz. fl.) is a unit of volume (also called capacity) typically used for measuring liquids. Various definitions have been used throughout history, but only two are still in common use: the British Imperial and the United States customary fluid ounce. An imperial fluid ounce is 1⁄20 of an imperial pint, 1⁄160 of an imperial gallon or approximately 28.4 ml. The fluid ounce is distinct from the ounce as a unit of weight or mass, although it is sometimes referred to simply as an "ounce" where context makes the meaning clear, such as ounces in a bottle.
-
Cubic Inch (0.01638706L)
The cubic inch (symbol in³) 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 three dimensions (length, width, and depth) being one inch long.
-
US Tablespoon (0.01478676L)
A tablespoon is a large spoon used for serving or eating. In many English-speaking regions, the term now refers to a large spoon used for serving, however, in some regions, including parts of Canada, it is the largest type of spoon used for eating. By extension, the term is used as a measure of volume in cooking. In this capacity, it is most commonly abbreviated tbsp or T, and occasionally referred to as a tablespoonful to distinguish it from the utensil. The unit of measurement varies by region: a United States tablespoon is approximately 14.8 ml (0.50 US fl oz). The capacity of the utensil (as opposed to the measurement) is not defined by law or custom and bears no particular relation to the measurement.

UK Tablespoon (0.01420654L)
A tablespoon is a large spoon used for serving or eating. In many English-speaking regions, the term now refers to a large spoon used for serving, however, in some regions, including parts of Canada, it is the largest type of spoon used for eating. By extension, the term is used as a measure of volume in cooking. In this capacity, it is most commonly abbreviated tbsp or T, and occasionally referred to as a tablespoonful to distinguish it from the utensil. The unit of measurement varies by region: a United Kingdom and Canadian tablespoon is exactly 15 ml (0.51 US fl oz), and an Australian tablespoon is 20 ml (0.68 US fl oz). The capacity of the utensil (as opposed to the measurement) is not defined by law or custom and bears no particular relation to the measurement.

Centiliter (0.01L)
1/100 of a litre.
-
Metric Teaspoon (0.005L)
The metric teaspoon as a unit of culinary measure is 5 mL, equal to 5 cm3; that is, 1⁄3 UK/Canadian metric tablespoon, or 1⁄4 Australian metric tablespoon.
-
US Teaspoon (0.004928922L)
A teaspoon is an item of cutlery, a measuring instrument, of approximately 5ml, or a unit of measurement of volume (usually abbreviated tsp.). In the United States one teaspoon as a unit of culinary measure is 1⁄3 tablespoon, that is, exactly 4.92892159375 mL; it is exactly 1 1⁄3 US fluid drams, 1⁄6 US fl oz, 1⁄48 US cup, and 1⁄768 US liquid gallon and 77⁄256 or 0.30078125 cubic inches. For nutritional labeling and medicine in the US, the teaspoon is defined as precisely 5 milliliters (mL), the same as a metric teaspoon (below). Common cutlery teaspoons are not designed to contain a standard volume. In practice, they may hold anything between 2.5 mL and 6 mL of liquid, so such spoons are not suitable for precise measurements, in particular for medicine. Measuring spoons should be used instead; medicine dose measuring spoons (5 mL) should be used for medicine.

UK Teaspoon (0.003551641L)
A teaspoon is an item of cutlery, a measuring instrument, of approximately 5ml, or a unit of measurement of volume (usually abbreviated tsp.).
-
Cubic Centimeter (0.001L)
A cubic centimetre (or cubic centimeter in US English) (SI unit symbol: cm3; non-SI abbreviations: cc and ccm) is a commonly used unit of volume that extends the derived SI-unit cubic metre, and corresponds to the volume of a cube that measures 1 cm × 1 cm × 1 cm. One cubic centimetre corresponds to a volume of 1/1,000,000 of a cubic metre, or 1/1,000 of a litre, or one millilitre; thus, 1 cm3 ≡ 1 ml. The mass of one cubic centimetre of water at 3.98 °C (the temperature at which it attains its maximum density) is closely equal to one gram. SI supports only the use of symbols and deprecates the use of any abbreviations for units. Hence cm3 is preferred to cc or ccm.
