About Converting Grains per Pint to Carats per Milliliter
Grain per Pint and Carat per Milliliter 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 milliliter = grains per pint × 0.000684722441811
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 milliliter equals 200 base units, so dividing one by the other gives the direct grain per pint-to-carat per milliliter factor of 0.000684722441811.
Simple example
1 gr/pt × 0.0006847224418 = 0.0006847224 ct/mL
1 grain per pint = 0.0006847224 carats per milliliter.
Real-world example
1,000 gr/pt × 0.0006847224418 = 0.6847224418 ct/mL
1,000 grains per pint = 0.6847224418 carats per milliliter.

Frequently asked questions
How many carats per milliliter are in 1 grain per pint?
1 grain per pint equals 0.0006847224 carats per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert grain per pint to carat per milliliter?
Multiply the grain per pint value by 0.0006847224418. The converter above does this instantly to whatever precision you set.
How do I convert carat per milliliter back to grain per pint?
Use the reverse factor: 1 carat per milliliter equals 1,460.445779 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 milliliter?
Carat per Milliliter (ct/mL) is a unit of density.
Is the grain per pint to carat per milliliter conversion exact?
Yes. Both grain per pint and carat per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 0.0006847224418 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.
