After any whole number of revolutions, the total displacement is zero
and so the average velocity is zero.
At any instant, the magnitude (speed component) of instantaneous velocity is
(pi) x (distance from center of rotation) x (RPM / 30) units per second.

To convert revolutions per minute (RPM) to linear velocity in meters per second (m/s), you need the radius of the rotating object. The linear velocity can be calculated by multiplying 2π times the RPM by the radius in meters, and then dividing by 60. The formula is: linear velocity (m/s) = 2π * RPM * radius (m) / 60.
The velocity of a rotating member can be calculated using the formula v = rω, where v is the linear velocity, r is the radius of rotation, and ω is the angular velocity in radians per second. Multiply the radius of rotation by the angular velocity to find the linear velocity of the rotating member.
The measure of speed in an engine is typically given in revolutions per minute (RPM). This indicates how many times the engine's crankshaft rotates within a minute. RPM is a key factor in determining the performance and power output of an engine.
While the unit most compatible with the SI (in the sense of simplifying mathematical formulae) would be radians per second, not only the U.S. but other parts of the world commonly use revolutions per minute.
No, the SI unit for radius is meters (m) and the SI unit for linear velocity is meters per second (m/s). Radius and linear velocity are related in rotational motion, where linear velocity is the tangential velocity at a certain radius from an axis of rotation.
RPM Revs Per Minute (how many times it spins round) is all to do with the cogs or gears linking the motor to the end shaft. The smaller the gear the greater rpm the bigger the gear the slower rpm. Someone although did tell me that 3000 rpm is 80 mph but that is false, it all depends on the gears.
