About Converting Stones per Fluid ounce to Grains per Cubic Centimeter
Stone per Fluid ounce and Grain 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
grains per cubic centimeter = stones per fluid ounce × 3313.77422478
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per fluid ounce equals 214728.957752 base units, and 1 grain per cubic centimeter equals 64.79891 base units, so dividing one by the other gives the direct stone per fluid ounce-to-grain per cubic centimeter factor of 3313.77422478.
Simple example
1 st/fl oz × 3313.774225 = 3,313.774225 gr/cm3
1 stone per fluid ounce = 3,313.774225 grains per cubic centimeter.
Real-world example
1,000 st/fl oz × 3313.774225 = 3,313,774.225 gr/cm3
1,000 stones per fluid ounce = 3,313,774.225 grains per cubic centimeter.

Frequently asked questions
How many grains per cubic centimeter are in 1 stone per fluid ounce?
1 stone per fluid ounce equals 3,313.774225 grains per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert stone per fluid ounce to grain per cubic centimeter?
Multiply the stone per fluid ounce value by 3313.774225. The converter above does this instantly to whatever precision you set.
How do I convert grain per cubic centimeter back to stone per fluid ounce?
Use the reverse factor: 1 grain per cubic centimeter equals 0.0003017707 stones per fluid ounce. You can also use the swap control in the converter above to flip the direction instantly.
What is a stone per fluid ounce?
Stone per Fluid ounce (st/fl oz) is a unit of density.
What is a grain per cubic centimeter?
Grain per Cubic Centimeter (gr/cm3) is a unit of density.
Is the stone per fluid ounce to grain per cubic centimeter conversion exact?
Yes. Both stone per fluid ounce and grain per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 3313.774225 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.
