Units explained
Imperial Quart
An imperial quart is one quarter of an imperial gallon (1.13652 L).
A subdivision of the 1824 imperial gallon.
Used in the UK and Commonwealth.
UK, 1824.
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.
