About Converting Drams per Cup to Grams per Cubic Millimeter
Dram per Cup and Gram per Cubic Millimeter 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
grams per cubic millimeter = drams per cup × 0.00000748915170731
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cup equals 7.48915170731 base units, and 1 gram per cubic millimeter equals 1000000 base units, so dividing one by the other gives the direct dram per cup-to-gram per cubic millimeter factor of 0.00000748915170731.
Simple example
1 dr/cup × 0.000007489151707 = 0.0000074892 g/mm3
1 dram per cup = 0.0000074892 grams per cubic millimeter.
Real-world example
1,000 dr/cup × 0.000007489151707 = 0.0074891517 g/mm3
1,000 drams per cup = 0.0074891517 grams per cubic millimeter.

Frequently asked questions
How many grams per cubic millimeter are in 1 dram per cup?
1 dram per cup equals 0.0000074892 grams per cubic millimeter, using the exact defined conversion factor rather than an estimate.
How do I convert dram per cup to gram per cubic millimeter?
Multiply the dram per cup value by 0.000007489151707. The converter above does this instantly to whatever precision you set.
How do I convert gram per cubic millimeter back to dram per cup?
Use the reverse factor: 1 gram per cubic millimeter equals 133,526.4712 drams per cup. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per cup?
Dram per Cup (dr/cup) is a unit of density.
What is a gram per cubic millimeter?
Gram per Cubic Millimeter (g/mm3) is a unit of density.
Is the dram per cup to gram per cubic millimeter conversion exact?
Yes. Both dram per cup and gram per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.000007489151707 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.
