FAQ

What is the conversion factor from gpm (US) to bbl/hr?
1 gpm (US) equals 1.428571 bbl/hr. To convert, multiply the value in US gallons per minute by 1.428571.
How do I convert 1 gpm (US) to bbl/hr?
1 gpm (US) = 1.42857 bbl/hr. For any value, multiply by 1.428571.
How do I convert bbl/hr back to gpm (US)?
Divide by the same factor — or equivalently, multiply by 0.7. So 1 bbl/hr = 0.7 gpm (US).
When would I need to convert US gallon per minute to oil barrel per hour?
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/hr 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).
