About Converting Carats per Gallon to Grain per Cubic inches
Carat per Gallon and Grain 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. Both are mass per volume density units.
Formula
grain per cubic inches = carats per gallon × 0.0133613492233
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per gallon equals 0.0528344104716 base units, and 1 grain per cubic inch equals 3.95427210146 base units, so dividing one by the other gives the direct carat per gallon-to-grain per cubic inch factor of 0.0133613492233.
Simple example
1 ct/gal × 0.01336134922 = 0.0133613492 gr/in3
1 carat per gallon = 0.0133613492 grain per cubic inches.
Real-world example
1,000 ct/gal × 0.01336134922 = 13.36134922 gr/in3
1,000 carats per gallon = 13.36134922 grain per cubic inches.

What is a carat per gallon?
Carat per Gallon (ct/gal) is a unit of density.
What is a grain per cubic inch?
Grain per Cubic inch (gr/in3) is a unit of density.
Is the carat per gallon to grain per cubic inch conversion exact?
Yes. Both carat per gallon and grain per cubic inch are defined by fixed standards rather than physical artifacts, so the factor of 0.01336134922 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.
