About Converting Pounds per Cup to Decagrams per Gallon
Pound per Cup and Decagram per Gallon 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
decagrams per gallon = pounds per cup × 725.747792
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cup equals 1917.22283707 base units, and 1 decagram per gallon equals 2.64172052358 base units, so dividing one by the other gives the direct pound per cup-to-decagram per gallon factor of 725.747792.
Simple example
1 lb/cup × 725.747792 = 725.747792 dag/gal
1 pound per cup = 725.747792 decagrams per gallon.
Real-world example
1,000 lb/cup × 725.747792 = 725,747.792 dag/gal
1,000 pounds per cup = 725,747.792 decagrams per gallon.

What is a pound per cup?
Pound per Cup (lb/cup) is a unit of density.
What is a decagram per gallon?
Decagram per Gallon (dag/gal) is a unit of density.
Is the pound per cup to decagram per gallon conversion exact?
Yes. Both pound per cup and decagram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 725.747792 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
