About Converting Deciliters to Quarts
Deciliter 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: Deciliter is 0.1 liter units, and a US liquid quart is one quarter of a US gallon.
Formula
quarts = deciliters × 0.105668820943
This factor comes from each unit's defined relationship to the category's base unit: 1 deciliter equals 0.0001 base units, and 1 quart equals 0.000946352946 base units, so dividing one by the other gives the direct deciliter-to-quart factor of 0.105668820943.
Simple example
1 dL × 0.1056688209 = 0.1056688209 qt
1 deciliter = 0.1056688209 quarts.
Real-world example
10 dL × 0.1056688209 = 1.056688209 qt
10 deciliters = 1.056688209 quarts.
