About Converting Stones per Gallon to Kilograms per Oil barrel
Stone per Gallon and Kilogram 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
kilograms per oil barrel = stones per gallon × 266.71231356
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per gallon equals 1677.56998244 base units, and 1 kilogram per oil barrel equals 6.28981077043 base units, so dividing one by the other gives the direct stone per gallon-to-kilogram per oil barrel factor of 266.71231356.
Simple example
1 st/gal × 266.7123136 = 266.7123136 kg/bbl
1 stone per gallon = 266.7123136 kilograms per oil barrel.
Real-world example
1,000 st/gal × 266.7123136 = 266,712.3136 kg/bbl
1,000 stones per gallon = 266,712.3136 kilograms per oil barrel.

What is a stone per gallon?
Stone per Gallon (st/gal) is a unit of density.
What is a kilogram per oil barrel?
Kilogram per Oil barrel (kg/bbl) is a unit of density.
Is the stone per gallon to kilogram per oil barrel conversion exact?
Yes. Both stone per gallon and kilogram per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 266.7123136 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.
