About Converting Oil barrel per Days to Oil barrel per Years
Oil barrel 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 = oil barrel per days × 365.2425
This factor comes from each unit's defined relationship to the category's base unit: 1 oil barrel per days equals 0.00000184013072833 base units, and 1 oil barrel per years equals 5.038107e-9 base units, so dividing one by the other gives the direct oil barrel per days-to-oil barrel per years factor of 365.2425.
Simple example
1 bbl/d × 365.2425 = 365.2425 bbl/yr
1 oil barrel per days = 365.2425 oil barrel per years.
Real-world example
60 bbl/d × 365.2425 = 21,914.55 bbl/yr
60 oil barrel per days = 21,914.55 oil barrel per years.

Multiply the oil barrel per days value by 365.2425. The converter above does this instantly to whatever precision you set.
How do I convert oil barrel per years back to oil barrel per days?
Use the reverse factor: 1 oil barrel per years equals 0.002737907 oil barrel per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a oil barrel per days?
Oil barrel per Days (bbl/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 oil barrel per days to oil barrel per years conversion exact?
Yes. Both oil barrel per days and oil barrel per years are defined by fixed standards rather than physical artifacts, so the factor of 365.2425 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.
