**About CC/REV to GPM Calculator (Formula)**

The CC/REV to GPM Calculator formula is used to convert a given flow rate from cubic centimeters per revolution (CC/REV) to gallons per minute (GPM) for a given rotational speed in RPM.

**The formula is:**

**GPM = CC/REV / 3785 * RPM**

Where GPM is the flow rate in gallons per minute, CC/REV is the flow rate in cubic centimeters per revolution, and RPM is the rotational speed in revolutions per minute.

Note that the constant 3785 is used to convert from cubic centimeters to gallons (1 cubic centimeter = 0.000264172 gallons), and the result is multiplied by RPM to take into account the rotational speed.
