About Converting Decagrams per Gallon to Pounds per Cup
Decagram per Gallon and Pound per Cup both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
pounds per cup = decagrams per gallon × 0.00137788913866
This factor comes from each unit's defined relationship to the category's base unit: 1 decagram per gallon equals 2.64172052358 base units, and 1 pound per cup equals 1917.22283707 base units, so dividing one by the other gives the direct decagram per gallon-to-pound per cup factor of 0.00137788913866.
Simple example
1 dag/gal × 0.001377889139 = 0.0013778891 lb/cup
1 decagram per gallon = 0.0013778891 pounds per cup.
Real-world example
1,000 dag/gal × 0.001377889139 = 1.377889139 lb/cup
1,000 decagrams per gallon = 1.377889139 pounds per cup.
