About Converting Stones per Gallon to Milligrams per Oil barrel
Stone per Gallon and Milligram 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
milligrams per oil barrel = stones per gallon × 266712313.56
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 milligram per oil barrel equals 0.00000628981077043 base units, so dividing one by the other gives the direct stone per gallon-to-milligram per oil barrel factor of 266712313.56.
Simple example
1 st/gal × 266712313.6 = 266,712,313.6 mg/bbl
1 stone per gallon = 266,712,313.6 milligrams per oil barrel.
Real-world example
1,000 st/gal × 266712313.6 = 266,712,313,600 mg/bbl
1,000 stones per gallon = 266,712,313,600 milligrams per oil barrel.

What is a stone per gallon?
Stone per Gallon (st/gal) is a unit of density.
What is a milligram per oil barrel?
Milligram per Oil barrel (mg/bbl) is a unit of density.
Is the stone per gallon to milligram per oil barrel conversion exact?
Yes. Both stone per gallon and milligram per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 266712313.6 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.
