About Converting Pound per Cubic inches to Decagrams per Cup
Pound per Cubic inch and Decagram 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. Pound per Cubic inch is most often used for used in machining and materials engineering, particularly for describing the density of metals, where a smaller volume unit than the cubic foot gives a more convenient figure.
Formula
decagrams per cup = pound per cubic inches × 654.873984188
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic inch equals 27679.9047102 base units, and 1 decagram per cup equals 42.2675283773 base units, so dividing one by the other gives the direct pound per cubic inch-to-decagram per cup factor of 654.873984188.
Simple example
1 lb/in3 × 654.8739842 = 654.8739842 dag/cup
1 pound per cubic inch = 654.8739842 decagrams per cup.
Real-world example
1,000 lb/in3 × 654.8739842 = 654,873.9842 dag/cup
1,000 pound per cubic inches = 654,873.9842 decagrams per cup.

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.
