About Converting Centigrams per Teaspoon to Grains per Gallon
Centigram per Teaspoon and Grain 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
grains per gallon = centigrams per teaspoon × 118.520512151
This factor comes from each unit's defined relationship to the category's base unit: 1 centigram per teaspoon equals 2.02884136211 base units, and 1 grain per gallon equals 0.0171180610453 base units, so dividing one by the other gives the direct centigram per teaspoon-to-grain per gallon factor of 118.520512151.
Simple example
1 cg/tsp × 118.5205122 = 118.5205122 gr/gal
1 centigram per teaspoon = 118.5205122 grains per gallon.
Real-world example
1,000 cg/tsp × 118.5205122 = 118,520.5122 gr/gal
1,000 centigrams per teaspoon = 118,520.5122 grains per gallon.

What is a centigram per teaspoon?
Centigram per Teaspoon (cg/tsp) is a unit of density.
What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
Is the centigram per teaspoon to grain per gallon conversion exact?
Yes. Both centigram per teaspoon and grain per gallon are defined by fixed standards rather than physical artifacts, so the factor of 118.5205122 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.
