About Converting Grains per Teaspoon to Stones per Gallon
Grain per Teaspoon and Stone 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
stones per gallon = grains per teaspoon × 0.00783673469388
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 stone per gallon equals 1677.56998244 base units, so dividing one by the other gives the direct grain per teaspoon-to-stone per gallon factor of 0.00783673469388.
Simple example
1 gr/tsp × 0.007836734694 = 0.0078367347 st/gal
1 grain per teaspoon = 0.0078367347 stones per gallon.
Real-world example
1,000 gr/tsp × 0.007836734694 = 7.836734694 st/gal
1,000 grains per teaspoon = 7.836734694 stones per gallon.

What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
What is a stone per gallon?
Stone per Gallon (st/gal) is a unit of density.
Is the grain per teaspoon to stone per gallon conversion exact?
Yes. Both grain per teaspoon and stone per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.007836734694 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.
