Units explained
Cubic Foot
A cubic foot is the volume of a cube one foot on a side (28.3168 L).
Derived by cubing the international foot (0.3048 m).
Used for natural gas, refrigerators, shipping and HVAC.
1959 yard agreement.
Cubic Decimeter
A cubic decimeter is the volume of a cube one decimeter on a side, exactly equal to one liter (0.001 m³).
Derived from the decimeter; in 1964 the CGPM defined the liter as exactly one cubic decimeter.
Common in chemistry and engineering as an exact synonym for the liter.
CGPM, 1964.
