About Converting Grains per Gallon to Pounds per Teaspoon
Grain per 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 gallon × 1.860119e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per gallon equals 0.0171180610453 base units, and 1 pound per teaspoon equals 92026.6961794 base units, so dividing one by the other gives the direct grain per gallon-to-pound per teaspoon factor of 1.860119e-7.
Simple example
1 gr/gal × 1.860119e-7 = 1.860119e-7 lb/tsp
1 grain per gallon = 1.860119e-7 pounds per teaspoon.
Real-world example
1,000 gr/gal × 1.860119e-7 = 0.0001860119 lb/tsp
1,000 grains per gallon = 0.0001860119 pounds per teaspoon.

Multiply the grain per gallon value by 1.860119e-7. The converter above does this instantly to whatever precision you set.
How do I convert pound per teaspoon back to grain per gallon?
Use the reverse factor: 1 pound per teaspoon equals 5,376,000 grains per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
What is a pound per teaspoon?
Pound per Teaspoon (lb/tsp) is a unit of density.
Is the grain per gallon to pound per teaspoon conversion exact?
Yes. Both grain per gallon and pound per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 1.860119e-7 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.
