About Converting Milligrams per Teaspoon to Grains per Imperial gallon
Milligram per Teaspoon 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 = milligrams per teaspoon × 14.2337200238
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per teaspoon equals 0.202884136211 base units, and 1 grain per imperial gallon equals 0.0142537675233 base units, so dividing one by the other gives the direct milligram per teaspoon-to-grain per imperial gallon factor of 14.2337200238.
Simple example
1 mg/tsp × 14.23372002 = 14.23372002 gr/imp gal
1 milligram per teaspoon = 14.23372002 grains per imperial gallon.
Real-world example
1,000 mg/tsp × 14.23372002 = 14,233.72002 gr/imp gal
1,000 milligrams per teaspoon = 14,233.72002 grains per imperial gallon.

What is a milligram per teaspoon?
Milligram per Teaspoon (mg/tsp) 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 milligram per teaspoon to grain per imperial gallon conversion exact?
Yes. Both milligram per teaspoon and grain per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 14.23372002 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.
