About Converting Dram per Cubic inches to Grains per Cubic Centimeter
Dram 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 = dram per cubic inches × 1.66861800259
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cubic inch equals 108.124627774 base units, and 1 grain per cubic centimeter equals 64.79891 base units, so dividing one by the other gives the direct dram per cubic inch-to-grain per cubic centimeter factor of 1.66861800259.
Simple example
1 dr/in3 × 1.668618003 = 1.668618003 gr/cm3
1 dram per cubic inch = 1.668618003 grains per cubic centimeter.
Real-world example
1,000 dr/in3 × 1.668618003 = 1,668.618003 gr/cm3
1,000 dram per cubic inches = 1,668.618003 grains per cubic centimeter.

Frequently asked questions
How many grains per cubic centimeter are in 1 dram per cubic inch?
1 dram per cubic inch equals 1.668618003 grains per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert dram per cubic inch to grain per cubic centimeter?
Multiply the dram per cubic inch value by 1.668618003. The converter above does this instantly to whatever precision you set.
How do I convert grain per cubic centimeter back to dram per cubic inch?
Use the reverse factor: 1 grain per cubic centimeter equals 0.5992983406 dram per cubic inches. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per cubic inch?
Dram per Cubic inch (dr/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 dram per cubic inch to grain per cubic centimeter conversion exact?
Yes. Both dram per cubic inch and grain per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 1.668618003 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.
