About Converting Hectograms per Oil barrel to Drams per Gallon
Hectogram per Oil barrel and Dram 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
drams per gallon = hectograms per oil barrel × 1.34376997903
This factor comes from each unit's defined relationship to the category's base unit: 1 hectogram per oil barrel equals 0.628981077043 base units, and 1 dram per gallon equals 0.468071981707 base units, so dividing one by the other gives the direct hectogram per oil barrel-to-dram per gallon factor of 1.34376997903.
Simple example
1 hg/bbl × 1.343769979 = 1.343769979 dr/gal
1 hectogram per oil barrel = 1.343769979 drams per gallon.
Real-world example
1,000 hg/bbl × 1.343769979 = 1,343.769979 dr/gal
1,000 hectograms per oil barrel = 1,343.769979 drams per gallon.

How do I convert dram per gallon back to hectogram per oil barrel?
Use the reverse factor: 1 dram per gallon equals 0.744174982 hectograms per oil barrel. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectogram per oil barrel?
Hectogram per Oil barrel (hg/bbl) is a unit of density.
What is a dram per gallon?
Dram per Gallon (dr/gal) is a unit of density.
Is the hectogram per oil barrel to dram per gallon conversion exact?
Yes. Both hectogram per oil barrel and dram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 1.343769979 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.
