About Converting Carats per Cubic foot to Grains per Gallon
Carat per Cubic foot and Grain per Gallon 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
grains per gallon = carats per cubic foot × 0.412601247631
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic foot equals 0.0070629333443 base units, and 1 grain per gallon equals 0.0171180610453 base units, so dividing one by the other gives the direct carat per cubic foot-to-grain per gallon factor of 0.412601247631.
Simple example
1 ct/ft3 × 0.4126012476 = 0.4126012476 gr/gal
1 carat per cubic foot = 0.4126012476 grains per gallon.
Real-world example
1,000 ct/ft3 × 0.4126012476 = 412.6012476 gr/gal
1,000 carats per cubic foot = 412.6012476 grains per gallon.

Multiply the carat per cubic foot value by 0.4126012476. The converter above does this instantly to whatever precision you set.
How do I convert grain per gallon back to carat per cubic foot?
Use the reverse factor: 1 grain per gallon equals 2.423647543 carats per cubic foot. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per cubic foot?
Carat per Cubic foot (ct/ft3) is a unit of density.
What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
Is the carat per cubic foot to grain per gallon conversion exact?
Yes. Both carat per cubic foot and grain per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.4126012476 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.
