About This Calculator
This calculator converts linear speed in meters per second (m/s) to rotational speed in revolutions per minute (RPM), using the specified radius in meters.
How It Works
- Input the linear speed in meters per second (m/s).
- Enter the radius of rotation in meters (m).
- The calculator uses the formula to instantly compute the equivalent RPM.
RPM =
60 × Linear Speed (m/s)2π × Radius (m)
Frequently Asked Questions
What is the difference between linear speed and rotational speed?
Linear speed measures how fast something moves along a straight path, while rotational speed measures how many full turns are made per minute around a central point.
Why do we multiply by 60 in the formula?
Multiplying by 60 converts seconds (used in m/s) to minutes, aligning with the RPM unit.
Can I use this calculator for any unit of radius?
No, the radius must be entered in meters to maintain correct unit consistency in the formula.
