FAQ

What is the conversion factor from bbl/day to cfs?
1 bbl/day equals 6.49836e-5 cfs. To convert, multiply the value in oil barrels per day by 6.49836e-5.
How do I convert 1 bbl/day to cfs?
1 bbl/day = 6.49836e-5 cfs. For any value, multiply by 6.49836e-5.
How do I convert cfs back to bbl/day?
Divide by the same factor — or equivalently, multiply by 15388.5. So 1 cfs = 15388.5 bbl/day.
When would I need to convert oil barrel per day to cubic foot per second?
Flow-rate conversions show up in pump curve interpretation, control valve sizing (Cv vs Kv), and aligning vendor specifications with process simulation outputs. bbl/day to cfs is a frequently needed conversion for flow datasheet preparation.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
