About Converting Milligrams per Imperial gallon to Grains per Teaspoon
Milligram per Imperial gallon and Grain per Teaspoon 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 teaspoon = milligrams per imperial gallon × 0.0000167319354277
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per imperial gallon equals 0.000219969248299 base units, and 1 grain per teaspoon equals 13.1466708828 base units, so dividing one by the other gives the direct milligram per imperial gallon-to-grain per teaspoon factor of 0.0000167319354277.
Simple example
1 mg/imp gal × 0.00001673193543 = 0.0000167319 gr/tsp
1 milligram per imperial gallon = 0.0000167319 grains per teaspoon.
Real-world example
1,000 mg/imp gal × 0.00001673193543 = 0.0167319354 gr/tsp
1,000 milligrams per imperial gallon = 0.0167319354 grains per teaspoon.

What is a milligram per imperial gallon?
Milligram per Imperial gallon (mg/imp gal) is a unit of density.
What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
Is the milligram per imperial gallon to grain per teaspoon conversion exact?
Yes. Both milligram per imperial gallon and grain per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.00001673193543 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.
