About Converting Grains per Cup to Centigrams per Cubic Centimeter
Grain per Cup and Centigram per Cubic Centimeter 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
centigrams per cubic centimeter = grains per cup × 0.0273888976724
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cup equals 0.273888976724 base units, and 1 centigram per cubic centimeter equals 10 base units, so dividing one by the other gives the direct grain per cup-to-centigram per cubic centimeter factor of 0.0273888976724.
Simple example
1 gr/cup × 0.02738889767 = 0.0273888977 cg/cm3
1 grain per cup = 0.0273888977 centigrams per cubic centimeter.
Real-world example
1,000 gr/cup × 0.02738889767 = 27.38889767 cg/cm3
1,000 grains per cup = 27.38889767 centigrams per cubic centimeter.

Frequently asked questions
How many centigrams per cubic centimeter are in 1 grain per cup?
1 grain per cup equals 0.0273888977 centigrams per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert grain per cup to centigram per cubic centimeter?
Multiply the grain per cup value by 0.02738889767. The converter above does this instantly to whatever precision you set.
How do I convert centigram per cubic centimeter back to grain per cup?
Use the reverse factor: 1 centigram per cubic centimeter equals 36.51114448 grains per cup. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per cup?
Grain per Cup (gr/cup) is a unit of density.
What is a centigram per cubic centimeter?
Centigram per Cubic Centimeter (cg/cm3) is a unit of density.
Is the grain per cup to centigram per cubic centimeter conversion exact?
Yes. Both grain per cup and centigram per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.02738889767 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.
