Formula

Formula
bbl/hr = gal/day (US) × 0.0009920635

Multiply any value in US gallons per day by 0.0009920635 to obtain the value in oil barrels per hour.

Worked example

Convert 10000 gal/day (US) to bbl/hr.

  1. 01Start with 10000 gal/day (US).
  2. 02Multiply by the conversion factor: 10000 × 0.0009920635 = 9.92063 bbl/hr.
Result10000 gal/day (US) = 9.92063 bbl/hr

FAQ

What is the conversion factor from gal/day (US) to bbl/hr?
1 gal/day (US) equals 0.0009920635 bbl/hr. To convert, multiply the value in US gallons per day by 0.0009920635.
How do I convert 1 gal/day (US) to bbl/hr?
1 gal/day (US) = 0.000992063 bbl/hr. For any value, multiply by 0.0009920635.
How do I convert bbl/hr back to gal/day (US)?
Divide by the same factor — or equivalently, multiply by 1008. So 1 bbl/hr = 1008 gal/day (US).
When would I need to convert US gallon per day 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. gal/day (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).
