## Full form of RPM | What does RPM stand for?

RPM Full Form – The full form of RPM is the Revolutions Per Minute. It is a measure of the frequency of rotation, the number of revolutions per minute. It tells how many times a mechanical component revolves around its axis in one minute. So, RPM is the rotational speed of a mechanical component such as the crankshaft of an engine, power generator turbine, CD or DVD player and turbocharger.
The term ‘RPM’ is widely used in cars, bikes, and aircraft. The more revolutions (rotation) the engine makes, the faster the vehicle goes, not to mention the increase in the throttle output.

When an engine starts, it burns air and gas to push the piston down. This makes the crankshaft spin, which ultimately drives the wheels of the vehicle. The automobile’s engine could stall if there is not enough RPM available, and too many rotations could hurt the engine, as well. If the tachometer is pointing to 1, it means the engine is rotating 1,000 times a minute. Based on different automobiles, the RPM limit varies. The limit area is displayed on the tachometer known as the ‘red line’.

The simple formula for calculating the RPM is as follows: RPM = r/min (where r represents the revolutions made by the object.) Also, 1 RPM in angular speed is equal to 2π/60 rad/s ≈ 0.1047198 rad/s.
