About Converting Pounds per Cubic foot to Decagrams per Quart
Pound per Cubic foot and Decagram per Quart 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 foot is most often used for us construction material density specs (concrete, soil, lumber, insulation).
Formula
decagrams per quart = pounds per cubic foot × 1.51591200043
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic foot equals 16.018463374 base units, and 1 decagram per quart equals 10.5668820943 base units, so dividing one by the other gives the direct pound per cubic foot-to-decagram per quart factor of 1.51591200043.
Simple example
1 lb/ft3 × 1.515912 = 1.515912 dag/qt
1 pound per cubic foot = 1.515912 decagrams per quart.
Real-world example
1,000 lb/ft3 × 1.515912 = 1,515.912 dag/qt
1,000 pounds per cubic foot = 1,515.912 decagrams per quart.

What is a pound per cubic foot?
Pound per Cubic foot (lb/ft3) measures density. The US customary unit for expressing density, commonly used in construction and engineering material specifications. It is classified as a US customary density unit.
What is a decagram per quart?
Decagram per Quart (dag/qt) is a unit of density.
Is the pound per cubic foot to decagram per quart conversion exact?
Yes. Both pound per cubic foot and decagram per quart are defined by fixed standards rather than physical artifacts, so the factor of 1.515912 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.
