Units explained
Liter
The liter is a metric unit of volume equal to one cubic decimeter (0.001 m³). It is the everyday metric volume unit.
Introduced in France in 1795; redefined in 1964 as exactly one cubic decimeter.
The world's common unit for beverages, fuel, and household liquids.
France, 1795; CGPM 1964.
US Quart
A US liquid quart is one quarter of a US gallon (0.946352946 L).
From the Latin quartus, a quarter of a gallon.
Used for milk, oil and household liquids in the US.
English customary.
