A volume converter changes capacity. This volume converter uses the cubic meter as the base. A liter is 0.001 m³. A milliliter is 1 cm³. Cubic inches and cubic feet use the international inch and foot, cubed. US liquid units follow the US gallon of 231 cubic inches, which is exactly 3.785411784 L. A US cup on this page is 1/16 of that gallon (8 US fluid ounces), not a 240 mL metric cup. Imperial units follow the Imperial gallon of 4.54609 L. An Imperial pint is 1/8 of that gallon. An Imperial fluid ounce is 1/160 of that gallon.
US and Imperial gallons are not interchangeable. A recipe or a fuel figure that says “gallon” without a country is unfinished. This page will not pick one for you. It also will not convert mass. A liter of honey is not a kilogram unless you supply density, and this page will not invent one.
Area is related only as the next-smaller dimension: the Area Converter squares a length. This page cubes it for cubic feet and cubic inches. It will not take a floor area and a height.
Negative volume is rejected. Zero is allowed. Empty and non-numeric input fail. Enter converts. Swap units exchanges the lists.
1 US gallon is 3.785411784 L. 1 Imperial gallon is 4.54609 L. 1 US cup is 236.5882365 mL. 1 Imperial pint is 568.26125 mL. 1 ft³ is 28.316846592 L.
1 US gal = 3.785411784 L
1 Imperial gal = 4.54609 L
1 US cup = 236.5882365 mLIf the label said gallon and you needed liters, pick the regional gallon first. Converting the wrong gallon and then blaming the liter is how tanks get ordered short.
US pints and quarts are halves and quarters of the US gallon. Imperial pints are halves of the Imperial gallon, so they are larger than US pints. A “pint of beer” in one country is not the pint on another country’s menu. Cubic feet are for rooms and ducts, not for a milk jug; you can still convert them to liters if the number is already a volume.
Engine displacements quoted in cubic inches or liters are volumes. This page will convert those two. It will not tell you horsepower. A tablespoon or a teaspoon is not listed because kitchen spoons vary; use milliliters from a measured spoon if you need SI. Swap US gallon and Imperial gallon on the same number if you need to see how far apart they sit: one US gallon is well under a liter-equivalent Imperial gallon, and the status will not call that close enough.
A US gallon is 231 cubic inches (3.785411784 L). An Imperial gallon is 4.54609 L. They are not interchangeable.
No. 3.785411784 L versus 4.54609 L.
The US customary cup of 8 US fluid ounces, not a 240 mL metric cup.
No. That needs density. This page only converts volume to volume.
Yes. Both are 0.000001 m³ on this page.
