About Converting Grams per Cubic foot to Carats per Quart
Gram per Cubic foot and Carat 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
carats per quart = grams per cubic foot × 0.167100694444
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 carat per quart equals 0.211337641887 base units, so dividing one by the other gives the direct gram per cubic foot-to-carat per quart factor of 0.167100694444.
Simple example
1 g/ft3 × 0.1671006944 = 0.1671006944 ct/qt
1 gram per cubic foot = 0.1671006944 carats per quart.
Real-world example
1,000 g/ft3 × 0.1671006944 = 167.1006944 ct/qt
1,000 grams per cubic foot = 167.1006944 carats 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 carats per quart are in 1 gram per cubic foot?
1 gram per cubic foot equals 0.1671006944 carats per quart, using the exact defined conversion factor rather than an estimate.
How do I convert gram per cubic foot to carat per quart?
Multiply the gram per cubic foot value by 0.1671006944. The converter above does this instantly to whatever precision you set.
How do I convert carat per quart back to gram per cubic foot?
Use the reverse factor: 1 carat per quart equals 5.984415584 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 carat per quart?
Carat per Quart (ct/qt) is a unit of density.
Is the gram per cubic foot to carat per quart conversion exact?
Yes. Both gram per cubic foot and carat per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.1671006944 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.
