Definition:

Rate of Fire (RPM) represents the maximum number of rounds a weapon can fire per minute in fully automatic mode (or the fastest firing mode available). It is a measure of how quickly the weapon can shoot, based on its internal reload cycle.

Formula:

$$\text{RPM} = \frac{60}{reloadTime}$$

Where:

  • reloadTime = the time (in seconds) it takes to chamber the next round in the current firing mode.
