About Converting Megagrams per Gallon to Megagrams per Oil barrel
Megagram per Gallon and Megagram 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
megagrams per oil barrel = megagrams per gallon × 42
This factor comes from each unit's defined relationship to the category's base unit: 1 megagram per gallon equals 264172.052358 base units, and 1 megagram per oil barrel equals 6289.81077043 base units, so dividing one by the other gives the direct megagram per gallon-to-megagram per oil barrel factor of 42.
Simple example
1 Mg/gal × 42 = 42 Mg/bbl
1 megagram per gallon = 42 megagrams per oil barrel.
Real-world example
1,000 Mg/gal × 42 = 42,000 Mg/bbl
1,000 megagrams per gallon = 42,000 megagrams per oil barrel.

Frequently asked questions
How many megagrams per oil barrel are in 1 megagram per gallon?
1 megagram per gallon equals 42 megagrams per oil barrel, using the exact defined conversion factor rather than an estimate.
How do I convert megagram per gallon to megagram per oil barrel?
Multiply the megagram per gallon value by 42. The converter above does this instantly to whatever precision you set.
How do I convert megagram per oil barrel back to megagram per gallon?
Use the reverse factor: 1 megagram per oil barrel equals 0.0238095238 megagrams per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a megagram per gallon?
Megagram per Gallon (Mg/gal) is a unit of density.
What is a megagram per oil barrel?
Megagram per Oil barrel (Mg/bbl) is a unit of density.
Is the megagram per gallon to megagram per oil barrel conversion exact?
Yes. Both megagram per gallon and megagram per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 42 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.
