About Converting Drams per Milliliter to Stones per Cup
Dram per Milliliter and Stone 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
stones per cup = drams per milliliter × 0.0660123427734
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per milliliter equals 1771.84519531 base units, and 1 stone per cup equals 26841.119719 base units, so dividing one by the other gives the direct dram per milliliter-to-stone per cup factor of 0.0660123427734.
Simple example
1 dr/mL × 0.06601234277 = 0.0660123428 st/cup
1 dram per milliliter = 0.0660123428 stones per cup.
Real-world example
1,000 dr/mL × 0.06601234277 = 66.01234277 st/cup
1,000 drams per milliliter = 66.01234277 stones per cup.

Frequently asked questions
How many stones per cup are in 1 dram per milliliter?
1 dram per milliliter equals 0.0660123428 stones per cup, using the exact defined conversion factor rather than an estimate.
How do I convert dram per milliliter to stone per cup?
Multiply the dram per milliliter value by 0.06601234277. The converter above does this instantly to whatever precision you set.
How do I convert stone per cup back to dram per milliliter?
Use the reverse factor: 1 stone per cup equals 15.14868217 drams per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per milliliter?
Dram per Milliliter (dr/mL) is a unit of density.
What is a stone per cup?
Stone per Cup (st/cup) is a unit of density.
Is the dram per milliliter to stone per cup conversion exact?
Yes. Both dram per milliliter and stone per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.06601234277 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.
