About Converting Long tons per Imperial gallon to Grains per Gallon
Long ton per Imperial gallon and Grain 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
grains per gallon = long tons per imperial gallon × 13056331.215
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per imperial gallon equals 223499.074765 base units, and 1 grain per gallon equals 0.0171180610453 base units, so dividing one by the other gives the direct long ton per imperial gallon-to-grain per gallon factor of 13056331.215.
Simple example
1 long ton/imp gal × 13056331.21 = 13,056,331.21 gr/gal
1 long ton per imperial gallon = 13,056,331.21 grains per gallon.
Real-world example
1,000 long ton/imp gal × 13056331.21 = 13,056,331,210 gr/gal
1,000 long tons per imperial gallon = 13,056,331,210 grains per gallon.

What is a long ton per imperial gallon?
Long ton per Imperial gallon (long ton/imp gal) is a unit of density.
What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
Is the long ton per imperial gallon to grain per gallon conversion exact?
Yes. Both long ton per imperial gallon and grain per gallon are defined by fixed standards rather than physical artifacts, so the factor of 13056331.21 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.
