About Converting Grain per Cubic inches to Drams per Cup
Grain per Cubic inch and Dram per Cup 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 cup = grain per cubic inches × 0.528
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cubic inch equals 3.95427210146 base units, and 1 dram per cup equals 7.48915170731 base units, so dividing one by the other gives the direct grain per cubic inch-to-dram per cup factor of 0.528.
Simple example
1 gr/in3 × 0.528 = 0.528 dr/cup
1 grain per cubic inch = 0.528 drams per cup.
Real-world example
1,000 gr/in3 × 0.528 = 528 dr/cup
1,000 grain per cubic inches = 528 drams per cup.

Frequently asked questions
How many drams per cup are in 1 grain per cubic inch?
1 grain per cubic inch equals 0.528 drams per cup, using the exact defined conversion factor rather than an estimate.
How do I convert grain per cubic inch to dram per cup?
Multiply the grain per cubic inch value by 0.528. The converter above does this instantly to whatever precision you set.
How do I convert dram per cup back to grain per cubic inch?
Use the reverse factor: 1 dram per cup equals 1.893939394 grain per cubic inches. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per cubic inch?
Grain per Cubic inch (gr/in3) is a unit of density.
What is a dram per cup?
Dram per Cup (dr/cup) is a unit of density.
Is the grain per cubic inch to dram per cup conversion exact?
Yes. Both grain per cubic inch and dram per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.528 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.
