About Converting Grains per Teaspoon to Drams per Gallon
Grain per Teaspoon and Dram per 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
drams per gallon = grains per teaspoon × 28.0868571429
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per teaspoon equals 13.1466708828 base units, and 1 dram per gallon equals 0.468071981707 base units, so dividing one by the other gives the direct grain per teaspoon-to-dram per gallon factor of 28.0868571429.
Simple example
1 gr/tsp × 28.08685714 = 28.08685714 dr/gal
1 grain per teaspoon = 28.08685714 drams per gallon.
Real-world example
1,000 gr/tsp × 28.08685714 = 28,086.85714 dr/gal
1,000 grains per teaspoon = 28,086.85714 drams per gallon.

How do I convert dram per gallon back to grain per teaspoon?
Use the reverse factor: 1 dram per gallon equals 0.0356038412 grains per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
What is a dram per gallon?
Dram per Gallon (dr/gal) is a unit of density.
Is the grain per teaspoon to dram per gallon conversion exact?
Yes. Both grain per teaspoon and dram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 28.08685714 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.
