About Converting Carats per Gallon to Grains per Teaspoon
Carat per Gallon 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 gallon × 0.00401884332108
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per gallon equals 0.0528344104716 base units, and 1 grain per teaspoon equals 13.1466708828 base units, so dividing one by the other gives the direct carat per gallon-to-grain per teaspoon factor of 0.00401884332108.
Simple example
1 ct/gal × 0.004018843321 = 0.0040188433 gr/tsp
1 carat per gallon = 0.0040188433 grains per teaspoon.
Real-world example
1,000 ct/gal × 0.004018843321 = 4.018843321 gr/tsp
1,000 carats per gallon = 4.018843321 grains per teaspoon.

What is a carat per gallon?
Carat per Gallon (ct/gal) 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 gallon to grain per teaspoon conversion exact?
Yes. Both carat per gallon and grain per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.004018843321 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.
