About Converting Ounce per Cubic inches to Grains per Cubic Centimeter
Ounce per Cubic inch 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 = ounce per cubic inches × 26.6978880414
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per cubic inch equals 1729.99404439 base units, and 1 grain per cubic centimeter equals 64.79891 base units, so dividing one by the other gives the direct ounce per cubic inch-to-grain per cubic centimeter factor of 26.6978880414.
Simple example
1 oz/in3 × 26.69788804 = 26.69788804 gr/cm3
1 ounce per cubic inch = 26.69788804 grains per cubic centimeter.
Real-world example
1,000 oz/in3 × 26.69788804 = 26,697.88804 gr/cm3
1,000 ounce per cubic inches = 26,697.88804 grains per cubic centimeter.

Multiply the ounce per cubic inch value by 26.69788804. The converter above does this instantly to whatever precision you set.
How do I convert grain per cubic centimeter back to ounce per cubic inch?
Use the reverse factor: 1 grain per cubic centimeter equals 0.0374561463 ounce per cubic inches. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per cubic inch?
Ounce per Cubic inch (oz/in3) 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 ounce per cubic inch to grain per cubic centimeter conversion exact?
Yes. Both ounce per cubic inch and grain per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 26.69788804 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.
