About Converting Slugs per Cubic foot to Stones per Oil barrel
Slug 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 = slugs per cubic foot × 12.9031340565
This factor comes from each unit's defined relationship to the category's base unit: 1 slug per cubic foot equals 515.378818393 base units, and 1 stone per oil barrel equals 39.942142439 base units, so dividing one by the other gives the direct slug per cubic foot-to-stone per oil barrel factor of 12.9031340565.
Simple example
1 slug/ft3 × 12.90313406 = 12.90313406 st/bbl
1 slug per cubic foot = 12.90313406 stones per oil barrel.
Real-world example
1,000 slug/ft3 × 12.90313406 = 12,903.13406 st/bbl
1,000 slugs per cubic foot = 12,903.13406 stones per oil barrel.

What is a slug per cubic foot?
Slug per Cubic foot (slug/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 slug per cubic foot to stone per oil barrel conversion exact?
Yes. Both slug per cubic foot and stone per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 12.90313406 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.
