About Converting Liters to Imperial quarts
Liter and Imperial quart appear side by side at fuel pumps and on beverage labels, since the US measures liquids in gallons while most of the world uses liters. Liter is typically associated with standard volume unit for liquids worldwide, including in the US for beverages and fuel labeling in some contexts, while Imperial quart is typically associated with united Kingdom and Commonwealth countries (historically).
Formula
imperial quarts = liters × 0.879876993196
This factor comes from each unit's defined relationship to the category's base unit: 1 liter equals 0.001 base units, and 1 imperial quart equals 0.0011365225 base units, so dividing one by the other gives the direct liter-to-imperial quart factor of 0.879876993196.
Simple example
1 L × 0.8798769932 = 0.8798769932 imp qt
1 liter = 0.8798769932 imperial quarts.
Real-world example
10 L × 0.8798769932 = 8.798769932 imp qt
10 liters = 8.798769932 imperial quarts.

Understanding the Liter
Liter (L) measures volume. A liter is defined as exactly one cubic decimeter (0.001 cubic meters). It is classified as a Non-SI metric unit accepted for use with SI.
Where it's used: Standard volume unit for liquids worldwide, including in the US for beverages and fuel labeling in some contexts
Uses of the Liter today
- Beverage, fuel, and liquid product packaging worldwide
- Cooking and recipe measurement in metric countries
- Laboratory and scientific volume measurement
History of the Liter
The liter was introduced with the French metric system in 1795, originally defined as the volume of one kilogram of pure water at its freezing point — tying volume, mass, and the meter together.
Between 1901 and 1964, the liter was briefly redefined as the volume of exactly one kilogram of water at its maximum density (about 4 °C), which made it very slightly larger than a cubic decimeter. It was redefined back to exactly one cubic decimeter in 1964, the definition still used today.
Historical origin. Liter was not the invention of a single named person; it developed through the process described above.
Understanding the Imperial quart
Imperial quart (imp qt) measures volume. The imperial quart is one-quarter of an imperial gallon: exactly 1.1365225 liters. It is classified as a UK/imperial customary unit.
Where it's used: United Kingdom and Commonwealth countries (historically)
Imperial quart vs. US quart. Like the gallon and pint, the imperial quart is about 20% larger than the US quart, following from Britain's 1824 gallon redefinition.
Uses of the Imperial quart today
- UK/Commonwealth liquid measurement in historical or specialized contexts
History of the Imperial quart
The imperial quart follows directly from the 1824 imperial gallon as one-quarter of it, part of the same UK standardization that diverged from the US gallon system.
Historical origin. Imperial quart was not the invention of a single named person; it developed through the process described above.
