About Converting Grams per Cubic foot to Carat per Cubic inches
Gram per Cubic foot and Carat per Cubic inch 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
carat per cubic inches = grams per cubic foot × 0.00289351851852
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 cubic inch equals 12.2047488189 base units, so dividing one by the other gives the direct gram per cubic foot-to-carat per cubic inch factor of 0.00289351851852.
Simple example
1 g/ft3 × 0.002893518519 = 0.0028935185 ct/in3
1 gram per cubic foot = 0.0028935185 carat per cubic inches.
Real-world example
1,000 g/ft3 × 0.002893518519 = 2.893518519 ct/in3
1,000 grams per cubic foot = 2.893518519 carat per cubic inches.

Frequently asked questions
How many carat per cubic inches are in 1 gram per cubic foot?
1 gram per cubic foot equals 0.0028935185 carat per cubic inches, using the exact defined conversion factor rather than an estimate.
How do I convert gram per cubic foot to carat per cubic inch?
Multiply the gram per cubic foot value by 0.002893518519. The converter above does this instantly to whatever precision you set.
How do I convert carat per cubic inch back to gram per cubic foot?
Use the reverse factor: 1 carat per cubic inch equals 345.6 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 cubic inch?
Carat per Cubic inch (ct/in3) is a unit of density.
Is the gram per cubic foot to carat per cubic inch conversion exact?
Yes. Both gram per cubic foot and carat per cubic inch are defined by fixed standards rather than physical artifacts, so the factor of 0.002893518519 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.
