About Converting Grams per Cubic foot to Pounds per Quart
Gram per Cubic foot and Pound 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. Gram per Cubic foot is most often used for can be used to express the density of low-density materials such as insulation foam, packaging material, or gas concentration by volume — for typical solid or liquid materials, kilograms per cubic meter or pounds per cubic foot are more commonly encountered.
Formula
pounds per quart = grams per cubic foot × 0.0000736787942198
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per cubic foot equals 0.0353146667215 base units, and 1 pound per quart equals 479.305709268 base units, so dividing one by the other gives the direct gram per cubic foot-to-pound per quart factor of 0.0000736787942198.
Simple example
1 g/ft3 × 0.00007367879422 = 0.0000736788 lb/qt
1 gram per cubic foot = 0.0000736788 pounds per quart.
Real-world example
1,000 g/ft3 × 0.00007367879422 = 0.0736787942 lb/qt
1,000 grams per cubic foot = 0.0736787942 pounds per quart.

Understanding the Gram per Cubic foot
Gram per Cubic foot (g/ft3) measures density. A gram is a small mass unit and a cubic foot a comparatively large volume, so this combination naturally suits low-density materials rather than typical solids or liquids. It is classified as a mixed metric/US customary density unit.

Frequently asked questions
How many pounds per quart are in 1 gram per cubic foot?
1 gram per cubic foot equals 0.0000736788 pounds per quart, using the exact defined conversion factor rather than an estimate.
How do I convert gram per cubic foot to pound per quart?
Multiply the gram per cubic foot value by 0.00007367879422. The converter above does this instantly to whatever precision you set.
How do I convert pound per quart back to gram per cubic foot?
Use the reverse factor: 1 pound per quart equals 13,572.42624 grams per cubic foot. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per cubic foot?
Gram per Cubic foot (g/ft3) measures density. A gram is a small mass unit and a cubic foot a comparatively large volume, so this combination naturally suits low-density materials rather than typical solids or liquids. It is classified as a mixed metric/US customary density unit.
What is a pound per quart?
Pound per Quart (lb/qt) is a unit of density.
Is the gram per cubic foot to pound per quart conversion exact?
Yes. Both gram per cubic foot and pound per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.00007367879422 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.
