About Converting Drams per Gallon to Grains per Teaspoon
Dram per 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 = drams per gallon × 0.0356038411458
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per gallon equals 0.468071981707 base units, and 1 grain per teaspoon equals 13.1466708828 base units, so dividing one by the other gives the direct dram per gallon-to-grain per teaspoon factor of 0.0356038411458.
Simple example
1 dr/gal × 0.03560384115 = 0.0356038412 gr/tsp
1 dram per gallon = 0.0356038412 grains per teaspoon.
Real-world example
1,000 dr/gal × 0.03560384115 = 35.60384115 gr/tsp
1,000 drams per gallon = 35.60384115 grains per teaspoon.

Multiply the dram per gallon value by 0.03560384115. The converter above does this instantly to whatever precision you set.
How do I convert grain per teaspoon back to dram per gallon?
Use the reverse factor: 1 grain per teaspoon equals 28.08685714 drams per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per gallon?
Dram per Gallon (dr/gal) is a unit of density.
What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
Is the dram per gallon to grain per teaspoon conversion exact?
Yes. Both dram per gallon and grain per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.03560384115 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.
