About Converting Grains per Cup to Short tons per Imperial gallon
Grain per Cup and Short ton 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
short tons per imperial gallon = grains per cup × 0.00000137251420058
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cup equals 0.273888976724 base units, and 1 short ton per imperial gallon equals 199552.745326 base units, so dividing one by the other gives the direct grain per cup-to-short ton per imperial gallon factor of 0.00000137251420058.
Simple example
1 gr/cup × 0.000001372514201 = 0.0000013725 ton/imp gal
1 grain per cup = 0.0000013725 short tons per imperial gallon.
Real-world example
1,000 gr/cup × 0.000001372514201 = 0.0013725142 ton/imp gal
1,000 grains per cup = 0.0013725142 short tons per imperial gallon.

What is a grain per cup?
Grain per Cup (gr/cup) is a unit of density.
What is a short ton per imperial gallon?
Short ton per Imperial gallon (ton/imp gal) is a unit of density.
Is the grain per cup to short ton per imperial gallon conversion exact?
Yes. Both grain per cup and short ton per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.000001372514201 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.
