About Converting Carats per Pint to Grains per Teaspoon
Carat per Pint and Grain per Teaspoon 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 teaspoon = carats per pint × 0.0321507465686
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 teaspoon equals 13.1466708828 base units, so dividing one by the other gives the direct carat per pint-to-grain per teaspoon factor of 0.0321507465686.
Simple example
1 ct/pt × 0.03215074657 = 0.0321507466 gr/tsp
1 carat per pint = 0.0321507466 grains per teaspoon.
Real-world example
1,000 ct/pt × 0.03215074657 = 32.15074657 gr/tsp
1,000 carats per pint = 32.15074657 grains per teaspoon.

What is a carat per pint?
Carat per Pint (ct/pt) is a unit of density.
What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
Is the carat per pint to grain per teaspoon conversion exact?
Yes. Both carat per pint and grain per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.03215074657 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.
