About Converting Grains per Milliliter to Carats per Pint
Grain per Milliliter 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 milliliter × 153.30659844
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per milliliter equals 64.79891 base units, and 1 carat per pint equals 0.422675283773 base units, so dividing one by the other gives the direct grain per milliliter-to-carat per pint factor of 153.30659844.
Simple example
1 gr/mL × 153.3065984 = 153.3065984 ct/pt
1 grain per milliliter = 153.3065984 carats per pint.
Real-world example
1,000 gr/mL × 153.3065984 = 153,306.5984 ct/pt
1,000 grains per milliliter = 153,306.5984 carats per pint.

Frequently asked questions
How many carats per pint are in 1 grain per milliliter?
1 grain per milliliter equals 153.3065984 carats per pint, using the exact defined conversion factor rather than an estimate.
How do I convert grain per milliliter to carat per pint?
Multiply the grain per milliliter value by 153.3065984. The converter above does this instantly to whatever precision you set.
How do I convert carat per pint back to grain per milliliter?
Use the reverse factor: 1 carat per pint equals 0.0065228764 grains per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per milliliter?
Grain per Milliliter (gr/mL) 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 milliliter to carat per pint conversion exact?
Yes. Both grain per milliliter and carat per pint are defined by fixed standards rather than physical artifacts, so the factor of 153.3065984 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.
