Volume Units

International System of Units (SI)

The basic unit of volume measurement in the metric system of measurements is the cubic meter [m³].
  The units derived from it are also used:

• 1 decimeter³ [dm³] = 0.001 m³.
• 1 centimeter³ [cm³] = 0.001 dm³.
• 1 millimeter³ [mm³] = 0.001 cm³.

In metrological measurements, also non-SI unit - liter, as well as derivatives from it are widely used.

• 1 Liter [L] = 1 dm³ = 0.001 m³.
• 1 Hectoliter [hL] = 100 liters = 100 dm³.
• 1 Decalitre [daL] = 10 liters.
• 1 Deciliter [dL] = 0.1 liters.
• 1 Centiliter [cL] = 0.01 liters.
• 1 Millilitre [mL] = 0.001 liters.
• 1 Microliter [μL] = 0.001 ml.

United States and Britain

• 1 yard³ [yd³] = 0.764554857984 m³ (exactly) = 27 feet³.
• 1 ft³ = 28.316846592 dm³ = 1728 inches³.
• 1 inch³ [in³] = 16.387064 cm³.

• 1 Barrel [bbl] oil = 119.240471 dm³.
• 1 Gallon [gal] = 3.785411784 dm³.
