About Converting Dram per Cubic inches to Grains per Teaspoon
Dram per Cubic inch 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 = dram per cubic inches × 8.22448730469
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cubic inch equals 108.124627774 base units, and 1 grain per teaspoon equals 13.1466708828 base units, so dividing one by the other gives the direct dram per cubic inch-to-grain per teaspoon factor of 8.22448730469.
Simple example
1 dr/in3 × 8.224487305 = 8.224487305 gr/tsp
1 dram per cubic inch = 8.224487305 grains per teaspoon.
Real-world example
1,000 dr/in3 × 8.224487305 = 8,224.487305 gr/tsp
1,000 dram per cubic inches = 8,224.487305 grains per teaspoon.

What is a dram per cubic inch?
Dram per Cubic inch (dr/in3) 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 cubic inch to grain per teaspoon conversion exact?
Yes. Both dram per cubic inch and grain per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 8.224487305 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.
