About Converting Drams per Cup to Stones per Oil barrel
Dram per Cup and Stone per Oil barrel 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 oil barrel = drams per cup × 0.1875
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 stone per oil barrel equals 39.942142439 base units, so dividing one by the other gives the direct dram per cup-to-stone per oil barrel factor of 0.1875.
Simple example
1 dr/cup × 0.1875 = 0.1875 st/bbl
1 dram per cup = 0.1875 stones per oil barrel.
Real-world example
1,000 dr/cup × 0.1875 = 187.5 st/bbl
1,000 drams per cup = 187.5 stones per oil barrel.

Multiply the dram per cup value by 0.1875. The converter above does this instantly to whatever precision you set.
How do I convert stone per oil barrel back to dram per cup?
Use the reverse factor: 1 stone per oil barrel equals 5.333333333 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 stone per oil barrel?
Stone per Oil barrel (st/bbl) is a unit of density.
Is the dram per cup to stone per oil barrel conversion exact?
Yes. Both dram per cup and stone per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 0.1875 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.
