About Converting Oil barrel per Days to Cubic foot per Seconds
Oil barrel per Days and Cubic foot per Seconds 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
cubic foot per seconds = oil barrel per days × 0.0000649836033951
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 cubic foot per seconds equals 0.028316846592 base units, so dividing one by the other gives the direct oil barrel per days-to-cubic foot per seconds factor of 0.0000649836033951.
Simple example
1 bbl/d × 0.0000649836034 = 0.0000649836 ft3/s
1 oil barrel per days = 0.0000649836 cubic foot per seconds.
Real-world example
60 bbl/d × 0.0000649836034 = 0.0038990162 ft3/s
60 oil barrel per days = 0.0038990162 cubic foot per seconds.

Frequently asked questions
How many cubic foot per seconds are in 1 oil barrel per days?
1 oil barrel per days equals 0.0000649836 cubic foot per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert oil barrel per days to cubic foot per seconds?
Multiply the oil barrel per days value by 0.0000649836034. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per seconds back to oil barrel per days?
Use the reverse factor: 1 cubic foot per seconds equals 15,388.49722 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 cubic foot per seconds?
Cubic foot per Seconds (ft3/s) measures volumetric flow rate. One cubic foot of volume passing a point every second. It is classified as a US customary flow-rate unit.
Is the oil barrel per days to cubic foot per seconds conversion exact?
Yes. Both oil barrel per days and cubic foot per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0000649836034 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.
