About Converting Grains per Imperial gallon to Pounds per Teaspoon
Grain per Imperial gallon and Pound 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
pounds per teaspoon = grains per imperial gallon × 1.548873e-7
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 pound per teaspoon equals 92026.6961794 base units, so dividing one by the other gives the direct grain per imperial gallon-to-pound per teaspoon factor of 1.548873e-7.
Simple example
1 gr/imp gal × 1.548873e-7 = 1.548873e-7 lb/tsp
1 grain per imperial gallon = 1.548873e-7 pounds per teaspoon.
Real-world example
1,000 gr/imp gal × 1.548873e-7 = 0.0001548873 lb/tsp
1,000 grains per imperial gallon = 0.0001548873 pounds per teaspoon.
