About Converting Grams per Quart to Grams per Cubic foot
Gram per Quart and Gram per Cubic foot 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 cubic foot = grams per quart × 29.9220779221
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per quart equals 1.05668820943 base units, and 1 gram per cubic foot equals 0.0353146667215 base units, so dividing one by the other gives the direct gram per quart-to-gram per cubic foot factor of 29.9220779221.
Simple example
1 g/qt × 29.92207792 = 29.92207792 g/ft3
1 gram per quart = 29.92207792 grams per cubic foot.
Real-world example
1,000 g/qt × 29.92207792 = 29,922.07792 g/ft3
1,000 grams per quart = 29,922.07792 grams per cubic foot.

Mass per volume density.
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.
Uses of the Gram per Cubic foot today
- 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
Gram per Cubic foot — sources
- BIPM SI Brochure — Gram and cubic foot as units combinable to express density, though not a standard industry pairing for general materials.

Frequently asked questions
How many grams per cubic foot are in 1 gram per quart?
1 gram per quart equals 29.92207792 grams per cubic foot, using the exact defined conversion factor rather than an estimate.
How do I convert gram per quart to gram per cubic foot?
Multiply the gram per quart value by 29.92207792. The converter above does this instantly to whatever precision you set.
How do I convert gram per cubic foot back to gram per quart?
Use the reverse factor: 1 gram per cubic foot equals 0.0334201389 grams per quart. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per quart?
Gram per Quart (g/qt) is a unit of density.
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.
Is the gram per quart to gram per cubic foot conversion exact?
Yes. Both gram per quart and gram per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 29.92207792 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.
