About Converting Carats per Milliliter to Grains per Imperial gallon
Carat per Milliliter and Grain per Imperial 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 imperial gallon = carats per milliliter × 14031.3779969
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per milliliter equals 200 base units, and 1 grain per imperial gallon equals 0.0142537675233 base units, so dividing one by the other gives the direct carat per milliliter-to-grain per imperial gallon factor of 14031.3779969.
Simple example
1 ct/mL × 14031.378 = 14,031.378 gr/imp gal
1 carat per milliliter = 14,031.378 grains per imperial gallon.
Real-world example
1,000 ct/mL × 14031.378 = 14,031,378 gr/imp gal
1,000 carats per milliliter = 14,031,378 grains per imperial gallon.

Frequently asked questions
How many grains per imperial gallon are in 1 carat per milliliter?
1 carat per milliliter equals 14,031.378 grains per imperial gallon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per milliliter to grain per imperial gallon?
Multiply the carat per milliliter value by 14031.378. The converter above does this instantly to whatever precision you set.
How do I convert grain per imperial gallon back to carat per milliliter?
Use the reverse factor: 1 grain per imperial gallon equals 0.0000712688 carats per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per milliliter?
Carat per Milliliter (ct/mL) is a unit of density.
What is a grain per imperial gallon?
Grain per Imperial gallon (gr/imp gal) is a unit of density.
Is the carat per milliliter to grain per imperial gallon conversion exact?
Yes. Both carat per milliliter and grain per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 14031.378 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.
