Barrels Per Day To GPM Formula

The following formula is used to calculate the gallons per minute (GPM) for a given barrels per day (bbl/day).

GPM = (bbl / day × CF) / (24 × 60)

Variables:

  • GPM is US gallons per minute
  • bbl/day is petroleum barrels per day
  • CF is the conversion factor (42 US gallons per petroleum barrel)

To calculate the gallons per minute, multiply the barrels per day by the conversion factor. Then, divide the result by the number of minutes in a day (24 * 60).
