About Converting Stones per Gallon to Grains per Imperial gallon
Stone per Gallon and Grain per Imperial 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 imperial gallon = stones per gallon × 117693.092699
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per gallon equals 1677.56998244 base units, and 1 grain per imperial gallon equals 0.0142537675233 base units, so dividing one by the other gives the direct stone per gallon-to-grain per imperial gallon factor of 117693.092699.
Simple example
1 st/gal × 117693.0927 = 117,693.0927 gr/imp gal
1 stone per gallon = 117,693.0927 grains per imperial gallon.
Real-world example
1,000 st/gal × 117693.0927 = 117,693,092.7 gr/imp gal
1,000 stones per gallon = 117,693,092.7 grains per imperial gallon.

What is a stone per gallon?
Stone per Gallon (st/gal) is a unit of density.
What is a grain per imperial gallon?
Grain per Imperial gallon (gr/imp gal) is a unit of density.
Is the stone per gallon to grain per imperial gallon conversion exact?
Yes. Both stone per gallon and grain per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 117693.0927 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.
