About Converting Grains per Gallon to Carats per Pint
Grain per Gallon and Carat per Pint 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 pint = grains per gallon × 0.04049931875
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per gallon equals 0.0171180610453 base units, and 1 carat per pint equals 0.422675283773 base units, so dividing one by the other gives the direct grain per gallon-to-carat per pint factor of 0.04049931875.
Simple example
1 gr/gal × 0.04049931875 = 0.0404993188 ct/pt
1 grain per gallon = 0.0404993188 carats per pint.
Real-world example
1,000 gr/gal × 0.04049931875 = 40.49931875 ct/pt
1,000 grains per gallon = 40.49931875 carats per pint.

How do I convert carat per pint back to grain per gallon?
Use the reverse factor: 1 carat per pint equals 24.69177336 grains per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
What is a carat per pint?
Carat per Pint (ct/pt) is a unit of density.
Is the grain per gallon to carat per pint conversion exact?
Yes. Both grain per gallon and carat per pint are defined by fixed standards rather than physical artifacts, so the factor of 0.04049931875 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.
