About Converting Milligrams per Gallon to Slugs per Oil barrel
Milligram per Gallon and Slug 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
slugs per oil barrel = milligrams per gallon × 0.00000287791416599
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per gallon equals 0.000264172052358 base units, and 1 slug per oil barrel equals 91.792887877 base units, so dividing one by the other gives the direct milligram per gallon-to-slug per oil barrel factor of 0.00000287791416599.
Simple example
1 mg/gal × 0.000002877914166 = 0.0000028779 slug/bbl
1 milligram per gallon = 0.0000028779 slugs per oil barrel.
Real-world example
1,000 mg/gal × 0.000002877914166 = 0.0028779142 slug/bbl
1,000 milligrams per gallon = 0.0028779142 slugs per oil barrel.

What is a milligram per gallon?
Milligram per Gallon (mg/gal) is a unit of density.
What is a slug per oil barrel?
Slug per Oil barrel (slug/bbl) is a unit of density.
Is the milligram per gallon to slug per oil barrel conversion exact?
Yes. Both milligram per gallon and slug per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 0.000002877914166 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.
