About Converting Long tons per Gallon to Nanograms per Oil barrel
Long ton per Gallon and Nanogram 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
nanograms per oil barrel = long tons per gallon × 4.267397e+16
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per gallon equals 268411.19719 base units, and 1 nanogram per oil barrel equals 6.289811e-12 base units, so dividing one by the other gives the direct long ton per gallon-to-nanogram per oil barrel factor of 4.267397e+16.
Simple example
1 long ton/gal × 4.267397e+16 = 4.267397e+16 ng/bbl
1 long ton per gallon = 4.267397e+16 nanograms per oil barrel.
Real-world example
1,000 long ton/gal × 4.267397e+16 = 4.267397e+19 ng/bbl
1,000 long tons per gallon = 4.267397e+19 nanograms per oil barrel.

Multiply the long ton per gallon value by 4.267397e+16. The converter above does this instantly to whatever precision you set.
How do I convert nanogram per oil barrel back to long ton per gallon?
Use the reverse factor: 1 nanogram per oil barrel equals 2.343349e-17 long tons per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a long ton per gallon?
Long ton per Gallon (long ton/gal) is a unit of density.
What is a nanogram per oil barrel?
Nanogram per Oil barrel (ng/bbl) is a unit of density.
Is the long ton per gallon to nanogram per oil barrel conversion exact?
Yes. Both long ton per gallon and nanogram per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 4.267397e+16 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.
