About Converting Cubic foot per Days to Oil barrel per Years
Cubic foot 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 = cubic foot per days × 65.0524675325
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per days equals 3.277413e-7 base units, and 1 oil barrel per years equals 5.038107e-9 base units, so dividing one by the other gives the direct cubic foot per days-to-oil barrel per years factor of 65.0524675325.
Simple example
1 ft3/d × 65.05246753 = 65.05246753 bbl/yr
1 cubic foot per days = 65.05246753 oil barrel per years.
Real-world example
60 ft3/d × 65.05246753 = 3,903.148052 bbl/yr
60 cubic foot per days = 3,903.148052 oil barrel per years.

What is a cubic foot per days?
Cubic foot per Days (ft3/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 cubic foot per days to oil barrel per years conversion exact?
Yes. Both cubic foot per days and oil barrel per years are defined by fixed standards rather than physical artifacts, so the factor of 65.05246753 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.
