About Converting Quart per Days to Oil barrel per Years
Quart 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 = quart per days × 2.1740625
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per days equals 1.095316e-8 base units, and 1 oil barrel per years equals 5.038107e-9 base units, so dividing one by the other gives the direct quart per days-to-oil barrel per years factor of 2.1740625.
Simple example
1 qt/d × 2.1740625 = 2.1740625 bbl/yr
1 quart per days = 2.1740625 oil barrel per years.
Real-world example
60 qt/d × 2.1740625 = 130.44375 bbl/yr
60 quart per days = 130.44375 oil barrel per years.

Multiply the quart per days value by 2.1740625. The converter above does this instantly to whatever precision you set.
How do I convert oil barrel per years back to quart per days?
Use the reverse factor: 1 oil barrel per years equals 0.4599683772 quart per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per days?
Quart per Days (qt/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 quart per days to oil barrel per years conversion exact?
Yes. Both quart per days and oil barrel per years are defined by fixed standards rather than physical artifacts, so the factor of 2.1740625 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.
