About Converting Gallon per Months to Oil barrel per Years
Gallon per Months and Oil barrel per Years both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Both are volumetric flow rate units.
Formula
oil barrel per years = gallon per months × 0.285714285714
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per months equals 1.439459e-9 base units, and 1 oil barrel per years equals 5.038107e-9 base units, so dividing one by the other gives the direct gallon per months-to-oil barrel per years factor of 0.285714285714.
Simple example
1 gal/mo × 0.2857142857 = 0.2857142857 bbl/yr
1 gallon per months = 0.2857142857 oil barrel per years.
Real-world example
60 gal/mo × 0.2857142857 = 17.14285714 bbl/yr
60 gallon per months = 17.14285714 oil barrel per years.

How do I convert oil barrel per years back to gallon per months?
Use the reverse factor: 1 oil barrel per years equals 3.5 gallon per months. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per months?
Gallon per Months (gal/mo) is a unit of flow rate.
What is a oil barrel per years?
Oil barrel per Years (bbl/yr) is a unit of flow rate.
Is the gallon per months to oil barrel per years conversion exact?
Yes. Both gallon per months and oil barrel per years are defined by fixed standards rather than physical artifacts, so the factor of 0.2857142857 used above is exact to as many digits as you choose to display.
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
