Volume Conversion

Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic meter.

Volume Units Explained

  • Cubic Meter (m³): The SI derived unit of volume. It is the volume of a cube with edges one meter in length.
  • Liter (L): A metric unit of volume equal to one cubic decimeter (dm³), 1,000 cubic centimeters (cm³), or 1/1,000 cubic meter.
  • Milliliter (mL): Equal to 1/1000th of a liter. Equivalent to one cubic centimeter (cc).
  • Gallon (gal): A unit of volume in imperial units and United States customary units. There are three different definitions: the imperial gallon (≈ 4.546 L), the US gallon (≈ 3.785 L), and the US dry gallon (≈ 4.405 L). This tool uses the US Liquid Gallon.
  • Cup: A cooking measure of volume, commonly associated with cooking and serving sizes.

[!TIP]
Fun Fact: The litre was originally defined as the volume of one kilogram of pure water at clear standard conditions. This relationship (1 kg of water ≈ 1 L) makes mental conversions between mass and volume of water very easy!
