About Converting Carats per Teaspoon to Grains per Gallon
Carat per Teaspoon and Grain per Gallon 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 gallon = carats per teaspoon × 2370.41024301
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per teaspoon equals 40.5768272422 base units, and 1 grain per gallon equals 0.0171180610453 base units, so dividing one by the other gives the direct carat per teaspoon-to-grain per gallon factor of 2370.41024301.
Simple example
1 ct/tsp × 2370.410243 = 2,370.410243 gr/gal
1 carat per teaspoon = 2,370.410243 grains per gallon.
Real-world example
1,000 ct/tsp × 2370.410243 = 2,370,410.243 gr/gal
1,000 carats per teaspoon = 2,370,410.243 grains per gallon.

What is a carat per teaspoon?
Carat per Teaspoon (ct/tsp) is a unit of density.
What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
Is the carat per teaspoon to grain per gallon conversion exact?
Yes. Both carat per teaspoon and grain per gallon are defined by fixed standards rather than physical artifacts, so the factor of 2370.410243 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.
