About Converting Gallon per Days to Oil barrel per Years
Gallon per Days 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 days × 8.69625
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per days equals 4.381264e-8 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 days-to-oil barrel per years factor of 8.69625.
Simple example
1 gal/d × 8.69625 = 8.69625 bbl/yr
1 gallon per days = 8.69625 oil barrel per years.
Real-world example
60 gal/d × 8.69625 = 521.775 bbl/yr
60 gallon per days = 521.775 oil barrel per years.

How do I convert oil barrel per years back to gallon per days?
Use the reverse factor: 1 oil barrel per years equals 0.1149920943 gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per days?
Gallon per Days (gal/d) 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 days to oil barrel per years conversion exact?
Yes. Both gallon per days and oil barrel per years are defined by fixed standards rather than physical artifacts, so the factor of 8.69625 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.
