About Converting Pounds per Cubic Meter to Grams per Quart
Pound per Cubic Meter and Gram 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. Both are mass per volume density units.
Formula
grams per quart = pounds per cubic meter × 0.429258475633
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic meter equals 0.45359237 base units, and 1 gram per quart equals 1.05668820943 base units, so dividing one by the other gives the direct pound per cubic meter-to-gram per quart factor of 0.429258475633.
Simple example
1 lb/m3 × 0.4292584756 = 0.4292584756 g/qt
1 pound per cubic meter = 0.4292584756 grams per quart.
Real-world example
1,000 lb/m3 × 0.4292584756 = 429.2584756 g/qt
1,000 pounds per cubic meter = 429.2584756 grams per quart.

Multiply the pound per cubic meter value by 0.4292584756. The converter above does this instantly to whatever precision you set.
How do I convert gram per quart back to pound per cubic meter?
Use the reverse factor: 1 gram per quart equals 2.329598731 pounds per cubic meter. You can also use the swap control in the converter above to flip the direction instantly.
What is a pound per cubic meter?
Pound per Cubic Meter (lb/m3) is a unit of density.
What is a gram per quart?
Gram per Quart (g/qt) is a unit of density.
Is the pound per cubic meter to gram per quart conversion exact?
Yes. Both pound per cubic meter and gram per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.4292584756 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.
