About Converting Carats per Pint to Grains per Pint
Carat per Pint and Grain 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
grains per pint = carats per pint × 3.08647167059
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per pint equals 0.422675283773 base units, and 1 grain per pint equals 0.136944488362 base units, so dividing one by the other gives the direct carat per pint-to-grain per pint factor of 3.08647167059.
Simple example
1 ct/pt × 3.086471671 = 3.086471671 gr/pt
1 carat per pint = 3.086471671 grains per pint.
Real-world example
1,000 ct/pt × 3.086471671 = 3,086.471671 gr/pt
1,000 carats per pint = 3,086.471671 grains per pint.

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