About Converting Micrograms per Imperial gallon to Grains per Oil barrel
Microgram per Imperial gallon and Grain 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
grains per oil barrel = micrograms per imperial gallon × 0.000539705309154
This factor comes from each unit's defined relationship to the category's base unit: 1 microgram per imperial gallon equals 2.199692e-7 base units, and 1 grain per oil barrel equals 0.00040757288203 base units, so dividing one by the other gives the direct microgram per imperial gallon-to-grain per oil barrel factor of 0.000539705309154.
Simple example
1 ug/imp gal × 0.0005397053092 = 0.0005397053 gr/bbl
1 microgram per imperial gallon = 0.0005397053 grains per oil barrel.
Real-world example
1,000 ug/imp gal × 0.0005397053092 = 0.5397053092 gr/bbl
1,000 micrograms per imperial gallon = 0.5397053092 grains per oil barrel.

Multiply the microgram per imperial gallon value by 0.0005397053092. The converter above does this instantly to whatever precision you set.
How do I convert grain per oil barrel back to microgram per imperial gallon?
Use the reverse factor: 1 grain per oil barrel equals 1,852.863003 micrograms per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a microgram per imperial gallon?
Microgram per Imperial gallon (ug/imp gal) is a unit of density.
What is a grain per oil barrel?
Grain per Oil barrel (gr/bbl) is a unit of density.
Is the microgram per imperial gallon to grain per oil barrel conversion exact?
Yes. Both microgram per imperial gallon and grain per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 0.0005397053092 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.
