About Converting Long tons per Cubic foot to Slugs per Oil barrel
Long ton per Cubic foot 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 = long tons per cubic foot × 390.894749991
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per cubic foot equals 35881.3579577 base units, and 1 slug per oil barrel equals 91.792887877 base units, so dividing one by the other gives the direct long ton per cubic foot-to-slug per oil barrel factor of 390.894749991.
Simple example
1 long ton/ft3 × 390.89475 = 390.89475 slug/bbl
1 long ton per cubic foot = 390.89475 slugs per oil barrel.
Real-world example
1,000 long ton/ft3 × 390.89475 = 390,894.75 slug/bbl
1,000 long tons per cubic foot = 390,894.75 slugs per oil barrel.

What is a long ton per cubic foot?
Long ton per Cubic foot (long ton/ft3) 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 long ton per cubic foot to slug per oil barrel conversion exact?
Yes. Both long ton per cubic foot and slug per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 390.89475 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.
