About Converting Grains per Teaspoon to Carats per Gallon
Grain per Teaspoon and Carat 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
carats per gallon = grains per teaspoon × 248.8278144
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per teaspoon equals 13.1466708828 base units, and 1 carat per gallon equals 0.0528344104716 base units, so dividing one by the other gives the direct grain per teaspoon-to-carat per gallon factor of 248.8278144.
Simple example
1 gr/tsp × 248.8278144 = 248.8278144 ct/gal
1 grain per teaspoon = 248.8278144 carats per gallon.
Real-world example
1,000 gr/tsp × 248.8278144 = 248,827.8144 ct/gal
1,000 grains per teaspoon = 248,827.8144 carats per gallon.

What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
What is a carat per gallon?
Carat per Gallon (ct/gal) is a unit of density.
Is the grain per teaspoon to carat per gallon conversion exact?
Yes. Both grain per teaspoon and carat per gallon are defined by fixed standards rather than physical artifacts, so the factor of 248.8278144 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.
