About Converting Milligrams per Gallon to Picograms per Oil barrel
Milligram per Gallon and Picogram 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
picograms per oil barrel = milligrams per gallon × 42000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per gallon equals 0.000264172052358 base units, and 1 picogram per oil barrel equals 6.289811e-15 base units, so dividing one by the other gives the direct milligram per gallon-to-picogram per oil barrel factor of 42000000000.
Simple example
1 mg/gal × 42000000000 = 42,000,000,000 pg/bbl
1 milligram per gallon = 42,000,000,000 picograms per oil barrel.
Real-world example
1,000 mg/gal × 42000000000 = 4.2e+13 pg/bbl
1,000 milligrams per gallon = 4.2e+13 picograms per oil barrel.

Frequently asked questions
How many picograms per oil barrel are in 1 milligram per gallon?
1 milligram per gallon equals 42,000,000,000 picograms per oil barrel, using the exact defined conversion factor rather than an estimate.
How do I convert milligram per gallon to picogram per oil barrel?
Multiply the milligram per gallon value by 42000000000. The converter above does this instantly to whatever precision you set.
How do I convert picogram per oil barrel back to milligram per gallon?
Use the reverse factor: 1 picogram per oil barrel equals 2.380952e-11 milligrams per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a milligram per gallon?
Milligram per Gallon (mg/gal) is a unit of density.
What is a picogram per oil barrel?
Picogram per Oil barrel (pg/bbl) is a unit of density.
Is the milligram per gallon to picogram per oil barrel conversion exact?
Yes. Both milligram per gallon and picogram per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 42000000000 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.
