FAQ

What is the conversion factor from gpm (US) to bbl/day?
1 gpm (US) equals 34.28571 bbl/day. To convert, multiply the value in US gallons per minute by 34.28571.
How do I convert 1 gpm (US) to bbl/day?
1 gpm (US) = 34.2857 bbl/day. For any value, multiply by 34.28571.
How do I convert bbl/day back to gpm (US)?
Divide by the same factor — or equivalently, multiply by 0.02916667. So 1 bbl/day = 0.0291667 gpm (US).
When would I need to convert US gallon per minute to oil barrel per day?
Flow-rate conversions show up in pump curve interpretation, control valve sizing (Cv vs Kv), and aligning vendor specifications with process simulation outputs. gpm (US) to bbl/day 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).
