About Converting Nanograms per Oil barrel to Stones per Gallon
Nanogram per Oil barrel and Stone 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
stones per gallon = nanograms per oil barrel × 3.749358e-15
This factor comes from each unit's defined relationship to the category's base unit: 1 nanogram per oil barrel equals 6.289811e-12 base units, and 1 stone per gallon equals 1677.56998244 base units, so dividing one by the other gives the direct nanogram per oil barrel-to-stone per gallon factor of 3.749358e-15.
Simple example
1 ng/bbl × 3.749358e-15 = 3.749358e-15 st/gal
1 nanogram per oil barrel = 3.749358e-15 stones per gallon.
Real-world example
1,000 ng/bbl × 3.749358e-15 = 3.749358e-12 st/gal
1,000 nanograms per oil barrel = 3.749358e-12 stones per gallon.

Multiply the nanogram per oil barrel value by 3.749358e-15. The converter above does this instantly to whatever precision you set.
How do I convert stone per gallon back to nanogram per oil barrel?
Use the reverse factor: 1 stone per gallon equals 2.667123e+14 nanograms per oil barrel. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanogram per oil barrel?
Nanogram per Oil barrel (ng/bbl) is a unit of density.
What is a stone per gallon?
Stone per Gallon (st/gal) is a unit of density.
Is the nanogram per oil barrel to stone per gallon conversion exact?
Yes. Both nanogram per oil barrel and stone per gallon are defined by fixed standards rather than physical artifacts, so the factor of 3.749358e-15 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.
