About Converting Grains per Imperial gallon to Milligrams per Teaspoon
Grain per Imperial gallon and Milligram 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
milligrams per teaspoon = grains per imperial gallon × 0.0702557025379
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per imperial gallon equals 0.0142537675233 base units, and 1 milligram per teaspoon equals 0.202884136211 base units, so dividing one by the other gives the direct grain per imperial gallon-to-milligram per teaspoon factor of 0.0702557025379.
Simple example
1 gr/imp gal × 0.07025570254 = 0.0702557025 mg/tsp
1 grain per imperial gallon = 0.0702557025 milligrams per teaspoon.
Real-world example
1,000 gr/imp gal × 0.07025570254 = 70.25570254 mg/tsp
1,000 grains per imperial gallon = 70.25570254 milligrams per teaspoon.

Frequently asked questions
How many milligrams per teaspoon are in 1 grain per imperial gallon?
1 grain per imperial gallon equals 0.0702557025 milligrams per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert grain per imperial gallon to milligram per teaspoon?
Multiply the grain per imperial gallon value by 0.07025570254. The converter above does this instantly to whatever precision you set.
How do I convert milligram per teaspoon back to grain per imperial gallon?
Use the reverse factor: 1 milligram per teaspoon equals 14.23372002 grains per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per imperial gallon?
Grain per Imperial gallon (gr/imp gal) is a unit of density.
What is a milligram per teaspoon?
Milligram per Teaspoon (mg/tsp) is a unit of density.
Is the grain per imperial gallon to milligram per teaspoon conversion exact?
Yes. Both grain per imperial gallon and milligram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.07025570254 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.
