About Converting Grains per Cup to Drams per Cubic Centimeter
Grain per Cup and Dram 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
drams per cubic centimeter = grains per cup × 0.000154578389494
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 dram per cubic centimeter equals 1771.84519531 base units, so dividing one by the other gives the direct grain per cup-to-dram per cubic centimeter factor of 0.000154578389494.
Simple example
1 gr/cup × 0.0001545783895 = 0.0001545784 dr/cm3
1 grain per cup = 0.0001545784 drams per cubic centimeter.
Real-world example
1,000 gr/cup × 0.0001545783895 = 0.1545783895 dr/cm3
1,000 grains per cup = 0.1545783895 drams per cubic centimeter.

Frequently asked questions
How many drams per cubic centimeter are in 1 grain per cup?
1 grain per cup equals 0.0001545784 drams per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert grain per cup to dram per cubic centimeter?
Multiply the grain per cup value by 0.0001545783895. The converter above does this instantly to whatever precision you set.
How do I convert dram per cubic centimeter back to grain per cup?
Use the reverse factor: 1 dram per cubic centimeter equals 6,469.209592 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 dram per cubic centimeter?
Dram per Cubic Centimeter (dr/cm3) is a unit of density.
Is the grain per cup to dram per cubic centimeter conversion exact?
Yes. Both grain per cup and dram per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.0001545783895 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.
