About Converting Milligrams per Imperial gallon to Decigrams per Oil barrel
Milligram per Imperial gallon and Decigram 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
decigrams per oil barrel = milligrams per imperial gallon × 0.349723157544
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per imperial gallon equals 0.000219969248299 base units, and 1 decigram per oil barrel equals 0.000628981077043 base units, so dividing one by the other gives the direct milligram per imperial gallon-to-decigram per oil barrel factor of 0.349723157544.
Simple example
1 mg/imp gal × 0.3497231575 = 0.3497231575 dg/bbl
1 milligram per imperial gallon = 0.3497231575 decigrams per oil barrel.
Real-world example
1,000 mg/imp gal × 0.3497231575 = 349.7231575 dg/bbl
1,000 milligrams per imperial gallon = 349.7231575 decigrams per oil barrel.

Multiply the milligram per imperial gallon value by 0.3497231575. The converter above does this instantly to whatever precision you set.
How do I convert decigram per oil barrel back to milligram per imperial gallon?
Use the reverse factor: 1 decigram per oil barrel equals 2.859404585 milligrams per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a milligram per imperial gallon?
Milligram per Imperial gallon (mg/imp gal) is a unit of density.
What is a decigram per oil barrel?
Decigram per Oil barrel (dg/bbl) is a unit of density.
Is the milligram per imperial gallon to decigram per oil barrel conversion exact?
Yes. Both milligram per imperial gallon and decigram per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 0.3497231575 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.
