About Converting Grain per Cubic inches to Carats per Gallon
Grain per Cubic inch and Carat 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
carats per gallon = grain per cubic inches × 74.84274105
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cubic inch equals 3.95427210146 base units, and 1 carat per gallon equals 0.0528344104716 base units, so dividing one by the other gives the direct grain per cubic inch-to-carat per gallon factor of 74.84274105.
Simple example
1 gr/in3 × 74.84274105 = 74.84274105 ct/gal
1 grain per cubic inch = 74.84274105 carats per gallon.
Real-world example
1,000 gr/in3 × 74.84274105 = 74,842.74105 ct/gal
1,000 grain per cubic inches = 74,842.74105 carats per gallon.

How do I convert carat per gallon back to grain per cubic inch?
Use the reverse factor: 1 carat per gallon equals 0.0133613492 grain per cubic inches. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per cubic inch?
Grain per Cubic inch (gr/in3) is a unit of density.
What is a carat per gallon?
Carat per Gallon (ct/gal) is a unit of density.
Is the grain per cubic inch to carat per gallon conversion exact?
Yes. Both grain per cubic inch and carat per gallon are defined by fixed standards rather than physical artifacts, so the factor of 74.84274105 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.
