Formula

Formula
bbl/day = gal/day (US) × 0.02380952

Multiply any value in US gallons per day by 0.02380952 to obtain the value in oil barrels per day.

Worked example

Convert 4200 gal/day (US) to bbl/day.

  1. 01Start with 4200 gal/day (US).
  2. 02Multiply by the conversion factor: 4200 × 0.02380952 = 100 bbl/day.
Result4200 gal/day (US) = 100 bbl/day

FAQ

What is the conversion factor from gal/day (US) to bbl/day?
1 gal/day (US) equals 0.02380952 bbl/day. To convert, multiply the value in US gallons per day by 0.02380952.
How do I convert 1 gal/day (US) to bbl/day?
1 gal/day (US) = 0.0238095 bbl/day. For any value, multiply by 0.02380952.
How do I convert bbl/day back to gal/day (US)?
Divide by the same factor — or equivalently, multiply by 42. So 1 bbl/day = 42 gal/day (US).
When would I need to convert US gallon per day 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. gal/day (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).
