About Converting Grains per Pint to Carats per Pint
Grain per Pint 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 pint × 0.32399455
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per pint equals 0.136944488362 base units, and 1 carat per pint equals 0.422675283773 base units, so dividing one by the other gives the direct grain per pint-to-carat per pint factor of 0.32399455.
Simple example
1 gr/pt × 0.32399455 = 0.32399455 ct/pt
1 grain per pint = 0.32399455 carats per pint.
Real-world example
1,000 gr/pt × 0.32399455 = 323.99455 ct/pt
1,000 grains per pint = 323.99455 carats per pint.

Frequently asked questions
How many carats per pint are in 1 grain per pint?
1 grain per pint equals 0.32399455 carats per pint, using the exact defined conversion factor rather than an estimate.
How do I convert grain per pint to carat per pint?
Multiply the grain per pint value by 0.32399455. The converter above does this instantly to whatever precision you set.
How do I convert carat per pint back to grain per pint?
Use the reverse factor: 1 carat per pint equals 3.086471671 grains per pint. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per pint?
Grain per Pint (gr/pt) 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 pint to carat per pint conversion exact?
Yes. Both grain per pint and carat per pint are defined by fixed standards rather than physical artifacts, so the factor of 0.32399455 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.
