About Converting Grains per Tablespoon to Grams per Imperial gallon
Grain per Tablespoon and Gram 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
grams per imperial gallon = grains per tablespoon × 19.9219830111
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per tablespoon equals 4.38222362759 base units, and 1 gram per imperial gallon equals 0.219969248299 base units, so dividing one by the other gives the direct grain per tablespoon-to-gram per imperial gallon factor of 19.9219830111.
Simple example
1 gr/tbsp × 19.92198301 = 19.92198301 g/imp gal
1 grain per tablespoon = 19.92198301 grams per imperial gallon.
Real-world example
1,000 gr/tbsp × 19.92198301 = 19,921.98301 g/imp gal
1,000 grains per tablespoon = 19,921.98301 grams per imperial gallon.

What is a grain per tablespoon?
Grain per Tablespoon (gr/tbsp) is a unit of density.
What is a gram per imperial gallon?
Gram per Imperial gallon (g/imp gal) is a unit of density.
Is the grain per tablespoon to gram per imperial gallon conversion exact?
Yes. Both grain per tablespoon and gram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 19.92198301 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.
