About Converting Stones per Oil barrel to Stones per Cubic foot
Stone per Oil barrel and Stone per Cubic foot 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 cubic foot = stones per oil barrel × 0.178107606679
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per oil barrel equals 39.942142439 base units, and 1 stone per cubic foot equals 224.258487235 base units, so dividing one by the other gives the direct stone per oil barrel-to-stone per cubic foot factor of 0.178107606679.
Simple example
1 st/bbl × 0.1781076067 = 0.1781076067 st/ft3
1 stone per oil barrel = 0.1781076067 stones per cubic foot.
Real-world example
1,000 st/bbl × 0.1781076067 = 178.1076067 st/ft3
1,000 stones per oil barrel = 178.1076067 stones per cubic foot.

What is a stone per oil barrel?
Stone per Oil barrel (st/bbl) is a unit of density.
What is a stone per cubic foot?
Stone per Cubic foot (st/ft3) is a unit of density.
Is the stone per oil barrel to stone per cubic foot conversion exact?
Yes. Both stone per oil barrel and stone per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 0.1781076067 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.
