About Converting Hectograms per Imperial gallon to Hectograms per Oil barrel
Hectogram per Imperial gallon and Hectogram 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
hectograms per oil barrel = hectograms per imperial gallon × 34.9723157544
This factor comes from each unit's defined relationship to the category's base unit: 1 hectogram per imperial gallon equals 21.9969248299 base units, and 1 hectogram per oil barrel equals 0.628981077043 base units, so dividing one by the other gives the direct hectogram per imperial gallon-to-hectogram per oil barrel factor of 34.9723157544.
Simple example
1 hg/imp gal × 34.97231575 = 34.97231575 hg/bbl
1 hectogram per imperial gallon = 34.97231575 hectograms per oil barrel.
Real-world example
1,000 hg/imp gal × 34.97231575 = 34,972.31575 hg/bbl
1,000 hectograms per imperial gallon = 34,972.31575 hectograms per oil barrel.

Frequently asked questions
How many hectograms per oil barrel are in 1 hectogram per imperial gallon?
1 hectogram per imperial gallon equals 34.97231575 hectograms per oil barrel, using the exact defined conversion factor rather than an estimate.
How do I convert hectogram per imperial gallon to hectogram per oil barrel?
Multiply the hectogram per imperial gallon value by 34.97231575. The converter above does this instantly to whatever precision you set.
How do I convert hectogram per oil barrel back to hectogram per imperial gallon?
Use the reverse factor: 1 hectogram per oil barrel equals 0.0285940459 hectograms per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectogram per imperial gallon?
Hectogram per Imperial gallon (hg/imp gal) is a unit of density.
What is a hectogram per oil barrel?
Hectogram per Oil barrel (hg/bbl) is a unit of density.
Is the hectogram per imperial gallon to hectogram per oil barrel conversion exact?
Yes. Both hectogram per imperial gallon and hectogram per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 34.97231575 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.
