About Converting Grains per Cubic Centimeter to Stones per Cup
Grain per Cubic Centimeter and Stone per Cup 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
stones per cup = grains per cubic centimeter × 0.00241416567857
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cubic centimeter equals 64.79891 base units, and 1 stone per cup equals 26841.119719 base units, so dividing one by the other gives the direct grain per cubic centimeter-to-stone per cup factor of 0.00241416567857.
Simple example
1 gr/cm3 × 0.002414165679 = 0.0024141657 st/cup
1 grain per cubic centimeter = 0.0024141657 stones per cup.
Real-world example
1,000 gr/cm3 × 0.002414165679 = 2.414165679 st/cup
1,000 grains per cubic centimeter = 2.414165679 stones per cup.

Frequently asked questions
How many stones per cup are in 1 grain per cubic centimeter?
1 grain per cubic centimeter equals 0.0024141657 stones per cup, using the exact defined conversion factor rather than an estimate.
How do I convert grain per cubic centimeter to stone per cup?
Multiply the grain per cubic centimeter value by 0.002414165679. The converter above does this instantly to whatever precision you set.
How do I convert stone per cup back to grain per cubic centimeter?
Use the reverse factor: 1 stone per cup equals 414.2217781 grains per cubic centimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per cubic centimeter?
Grain per Cubic Centimeter (gr/cm3) is a unit of density.
What is a stone per cup?
Stone per Cup (st/cup) is a unit of density.
Is the grain per cubic centimeter to stone per cup conversion exact?
Yes. Both grain per cubic centimeter and stone per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.002414165679 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.
