About Converting Milligrams per Imperial gallon to Stones per Oil barrel
Milligram per Imperial gallon 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 = milligrams per imperial gallon × 0.00000550719703219
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per imperial gallon equals 0.000219969248299 base units, and 1 stone per oil barrel equals 39.942142439 base units, so dividing one by the other gives the direct milligram per imperial gallon-to-stone per oil barrel factor of 0.00000550719703219.
Simple example
1 mg/imp gal × 0.000005507197032 = 0.0000055072 st/bbl
1 milligram per imperial gallon = 0.0000055072 stones per oil barrel.
Real-world example
1,000 mg/imp gal × 0.000005507197032 = 0.005507197 st/bbl
1,000 milligrams per imperial gallon = 0.005507197 stones per oil barrel.

What is a milligram per imperial gallon?
Milligram per Imperial gallon (mg/imp gal) 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 milligram per imperial gallon to stone per oil barrel conversion exact?
Yes. Both milligram per imperial gallon and stone per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 0.000005507197032 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.
