About Converting Stones per Oil barrel to Kilograms per Quart
Stone per Oil barrel and Kilogram per Quart 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
kilograms per quart = stones per oil barrel × 0.0377993641667
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 kilogram per quart equals 1056.68820943 base units, so dividing one by the other gives the direct stone per oil barrel-to-kilogram per quart factor of 0.0377993641667.
Simple example
1 st/bbl × 0.03779936417 = 0.0377993642 kg/qt
1 stone per oil barrel = 0.0377993642 kilograms per quart.
Real-world example
1,000 st/bbl × 0.03779936417 = 37.79936417 kg/qt
1,000 stones per oil barrel = 37.79936417 kilograms per quart.

What is a stone per oil barrel?
Stone per Oil barrel (st/bbl) is a unit of density.
What is a kilogram per quart?
Kilogram per Quart (kg/qt) is a unit of density.
Is the stone per oil barrel to kilogram per quart conversion exact?
Yes. Both stone per oil barrel and kilogram per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.03779936417 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.
