About Converting Grains per Teaspoon to Centigram per Cubic inches
Grain per Teaspoon and Centigram per Cubic inch 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
centigram per cubic inches = grains per teaspoon × 21.5435337143
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 centigram per cubic inch equals 0.610237440947 base units, so dividing one by the other gives the direct grain per teaspoon-to-centigram per cubic inch factor of 21.5435337143.
Simple example
1 gr/tsp × 21.54353371 = 21.54353371 cg/in3
1 grain per teaspoon = 21.54353371 centigram per cubic inches.
Real-world example
1,000 gr/tsp × 21.54353371 = 21,543.53371 cg/in3
1,000 grains per teaspoon = 21,543.53371 centigram per cubic inches.

What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
What is a centigram per cubic inch?
Centigram per Cubic inch (cg/in3) is a unit of density.
Is the grain per teaspoon to centigram per cubic inch conversion exact?
Yes. Both grain per teaspoon and centigram per cubic inch are defined by fixed standards rather than physical artifacts, so the factor of 21.54353371 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.
