About Converting Stones per Oil barrel to Megagrams per Gallon
Stone per Oil barrel and Megagram per Gallon 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
megagrams per gallon = stones per oil barrel × 0.000151197456667
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 megagram per gallon equals 264172.052358 base units, so dividing one by the other gives the direct stone per oil barrel-to-megagram per gallon factor of 0.000151197456667.
Simple example
1 st/bbl × 0.0001511974567 = 0.0001511975 Mg/gal
1 stone per oil barrel = 0.0001511975 megagrams per gallon.
Real-world example
1,000 st/bbl × 0.0001511974567 = 0.1511974567 Mg/gal
1,000 stones per oil barrel = 0.1511974567 megagrams per gallon.

Multiply the stone per oil barrel value by 0.0001511974567. The converter above does this instantly to whatever precision you set.
How do I convert megagram per gallon back to stone per oil barrel?
Use the reverse factor: 1 megagram per gallon equals 6,613.867866 stones per oil barrel. You can also use the swap control in the converter above to flip the direction instantly.
What is a stone per oil barrel?
Stone per Oil barrel (st/bbl) is a unit of density.
What is a megagram per gallon?
Megagram per Gallon (Mg/gal) is a unit of density.
Is the stone per oil barrel to megagram per gallon conversion exact?
Yes. Both stone per oil barrel and megagram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.0001511974567 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.
