About Converting Centigrams per Cup to Grains per Teaspoon
Centigram per Cup 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 = centigrams per cup × 0.00321507465686
This factor comes from each unit's defined relationship to the category's base unit: 1 centigram per cup equals 0.0422675283773 base units, and 1 grain per teaspoon equals 13.1466708828 base units, so dividing one by the other gives the direct centigram per cup-to-grain per teaspoon factor of 0.00321507465686.
Simple example
1 cg/cup × 0.003215074657 = 0.0032150747 gr/tsp
1 centigram per cup = 0.0032150747 grains per teaspoon.
Real-world example
1,000 cg/cup × 0.003215074657 = 3.215074657 gr/tsp
1,000 centigrams per cup = 3.215074657 grains per teaspoon.

Frequently asked questions
How many grains per teaspoon are in 1 centigram per cup?
1 centigram per cup equals 0.0032150747 grains per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert centigram per cup to grain per teaspoon?
Multiply the centigram per cup value by 0.003215074657. The converter above does this instantly to whatever precision you set.
How do I convert grain per teaspoon back to centigram per cup?
Use the reverse factor: 1 grain per teaspoon equals 311.034768 centigrams per cup. You can also use the swap control in the converter above to flip the direction instantly.
What is a centigram per cup?
Centigram per Cup (cg/cup) is a unit of density.
What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
Is the centigram per cup to grain per teaspoon conversion exact?
Yes. Both centigram per cup and grain per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.003215074657 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.
