About Converting Stones per Imperial gallon to Grains per Teaspoon
Stone per Imperial 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 = stones per imperial gallon × 106.252695434
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per imperial gallon equals 1396.86921728 base units, and 1 grain per teaspoon equals 13.1466708828 base units, so dividing one by the other gives the direct stone per imperial gallon-to-grain per teaspoon factor of 106.252695434.
Simple example
1 st/imp gal × 106.2526954 = 106.2526954 gr/tsp
1 stone per imperial gallon = 106.2526954 grains per teaspoon.
Real-world example
1,000 st/imp gal × 106.2526954 = 106,252.6954 gr/tsp
1,000 stones per imperial gallon = 106,252.6954 grains per teaspoon.

What is a stone per imperial gallon?
Stone per Imperial gallon (st/imp gal) is a unit of density.
What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
Is the stone per imperial gallon to grain per teaspoon conversion exact?
Yes. Both stone per imperial gallon and grain per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 106.2526954 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.
