About Converting Stones per Gallon to Slugs per Oil barrel
Stone 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 = stones per gallon × 18.2755987009
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 slug per oil barrel equals 91.792887877 base units, so dividing one by the other gives the direct stone per gallon-to-slug per oil barrel factor of 18.2755987009.
Simple example
1 st/gal × 18.2755987 = 18.2755987 slug/bbl
1 stone per gallon = 18.2755987 slugs per oil barrel.

What is a stone per gallon?
Stone per Gallon (st/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 stone per gallon to slug per oil barrel conversion exact?
