About Converting Hectoliters to Decaliters
Hectoliter and Decaliter 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: Hectoliter is 100 liter units, and decaliter is 10 liter units.
Formula
decaliters = hectoliters × 10
This factor comes from each unit's defined relationship to the category's base unit: 1 hectoliter equals 0.1 base units, and 1 decaliter equals 0.01 base units, so dividing one by the other gives the direct hectoliter-to-decaliter factor of 10.
Simple example
1 hL × 10 = 10 daL
1 hectoliter = 10 decaliters.
Real-world example
10 hL × 10 = 100 daL
10 hectoliters = 100 decaliters.
