About Converting Drams per Cubic foot to Stones per Oil barrel
Dram per Cubic foot 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 cubic foot × 0.00156656901042
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cubic foot equals 0.0625721225545 base units, and 1 stone per oil barrel equals 39.942142439 base units, so dividing one by the other gives the direct dram per cubic foot-to-stone per oil barrel factor of 0.00156656901042.
Simple example
1 dr/ft3 × 0.00156656901 = 0.001566569 st/bbl
1 dram per cubic foot = 0.001566569 stones per oil barrel.
Real-world example
1,000 dr/ft3 × 0.00156656901 = 1.56656901 st/bbl
1,000 drams per cubic foot = 1.56656901 stones per oil barrel.

What is a dram per cubic foot?
Dram per Cubic foot (dr/ft3) 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 cubic foot to stone per oil barrel conversion exact?
Yes. Both dram per cubic foot and stone per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 0.00156656901 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.
