About Converting Slugs per Gallon to Grains per Oil barrel
Slug per Gallon and Grain 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
grains per oil barrel = slugs per gallon × 9459170.27559
This factor comes from each unit's defined relationship to the category's base unit: 1 slug per gallon equals 3855.30129084 base units, and 1 grain per oil barrel equals 0.00040757288203 base units, so dividing one by the other gives the direct slug per gallon-to-grain per oil barrel factor of 9459170.27559.
Simple example
1 slug/gal × 9459170.276 = 9,459,170.276 gr/bbl
1 slug per gallon = 9,459,170.276 grains per oil barrel.
Real-world example
1,000 slug/gal × 9459170.276 = 9,459,170,276 gr/bbl
1,000 slugs per gallon = 9,459,170,276 grains per oil barrel.

What is a slug per gallon?
Slug per Gallon (slug/gal) is a unit of density.
What is a grain per oil barrel?
Grain per Oil barrel (gr/bbl) is a unit of density.
Is the slug per gallon to grain per oil barrel conversion exact?
Yes. Both slug per gallon and grain per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 9459170.276 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.
