Volume Units and Standards

Volume units can be divided into metric units (based on the liter and cubic meter) and customary units that vary between US and Imperial systems.

  • Cubic meter (m³): SI derived unit
  • Liter (L): 0.001 cubic meters
  • Milliliter (mL): 0.001 liters
  • US and Imperial gallons differ by about 20%

Understanding Volume Measurements

Volume measures the amount of three-dimensional space occupied by a substance or object. It's used for measuring liquids, gases, and solids, with different common units depending on the application and region. The SI derived unit for volume is the cubic meter (m³), though the liter (L) is more commonly used for everyday measurements.

Precision: 15 decimal places
Standard: ISO 80000-3:2019

Volume Units in Different Systems

Metric Volume Units

The metric system uses the liter as its main volume unit:

  • Cubic meter (m³): 1,000 liters
  • Liter (L): Base practical unit
  • Deciliter (dL): 0.1 liter
  • Centiliter (cL): 0.01 liter
  • Milliliter (mL): 0.001 liter (= 1 cubic centimeter)

US Customary Volume Units

The US system has distinct units for liquid and dry measurements:

  • Gallon: 4 quarts or 3.785 liters
  • Quart: 2 pints or 0.946 liters
  • Pint: 2 cups or 0.473 liters
  • Cup: 8 fluid ounces or 236.6 milliliters
  • Fluid ounce: 2 tablespoons or 29.57 milliliters
  • Tablespoon: 3 teaspoons or 14.79 milliliters

Imperial Volume Units

The British imperial system uses:

  • Imperial gallon: 4.546 liters
  • Imperial pint: 568.26 milliliters
  • Imperial fluid ounce: 28.41 milliliters

Note that these differ from their US counterparts!
