About Converting Cubic Decimeters to Quarts
Cubic Decimeter and 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. Specifically: Cubic metric volume unit, and a US liquid quart is one quarter of a US gallon.
Formula
quarts = cubic decimeters × 1.05668820943
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic decimeter equals 0.001 base units, and 1 quart equals 0.000946352946 base units, so dividing one by the other gives the direct cubic decimeter-to-quart factor of 1.05668820943.
Simple example
1 dm3 × 1.056688209 = 1.056688209 qt
1 cubic decimeter = 1.056688209 quarts.
Real-world example
10 dm3 × 1.056688209 = 10.56688209 qt
10 cubic decimeters = 10.56688209 quarts.

Understanding the Cubic Decimeter (dm3)
Cubic metric volume unit.
Understanding the Quart
Quart (qt) measures volume. The US liquid quart is exactly one-quarter of a US gallon: 0.946352946 liters. It is classified as a US customary unit.
Where it's used: United States (cooking, dairy, motor oil packaging)
Uses of the Quart today
- US recipe measurement (larger liquid volumes)
- US motor oil and automotive fluid packaging
- US dairy and beverage packaging (quart containers)
History of the Quart
The quart ('quarter' of a gallon) follows the same English wine-gallon lineage as the US gallon, retained by the US after England moved to a different imperial standard in 1824.
Historical origin. Quart was not the invention of a single named person; it developed through the process described above.
