Step 1:
: Understand the problem

To convert rotations per minute (RPM) to radians per second (rad/s), we need to use a conversion factor that relates the two units. The conversion factor is derived from the definition of radians and the relationship between the circumference of a circle and its radius.

Step 2:
: Find the conversion factor

- $60\; s$ is the time taken for one full rotation in seconds when the angular velocity is in RPM
The conversion factor from RPM to rad/s can be found using the following formula: Where:

Step 3:
: Apply the conversion factor

To convert a given angular velocity in RPM to rad/s, simply multiply the angular velocity in RPM by the conversion factor:

Step 4:
: Simplify the equation

We can simplify the equation by canceling out the units:

Step 5:
: Calculate the result

To calculate the angular velocity in rad/s, multiply the angular velocity in RPM by the simplified conversion factor:

Final Answer

To convert RPM to rad/s, multiply the angular velocity in RPM by the conversion factor $\frac{\pi}{30}$.
