Mechanics index               If quantities are measured in appropriate units, linear speed is simply angular speed multiplied by the radius of rotation. Centrifugal force is a fictitious force that is found by dividing the square of linear speed by the radius of rotation.              Angular speed: rad/s rad/h deg/s deg/h rpm rps (Hz) --- PERIOD --- s per rev mins per rev hours per rev Linear speed: m/s --- METRIC --- cm/s km/s -- IMPERIAL -- inches/second feet/second feet/minute - RECIPROCAL - min/mile min/km min/5 km min/10 km --- OTHER --- km/h mph miles/second knots furl's/f'night Mach c (light speed) Radius: m --- METRIC --- pm nm microns (µm) mm cm km -- IMPERIAL -- mil 1/16 inch inches feet yards miles - SCIENTIFIC - Planck Bohrs Angstrom light-seconds light-years au parsecs --- OTHER --- points cubits fathoms rods chains football fields furlongs Roman miles nautical miles leagues Angular speed: rad/s rad/h deg/s deg/h rpm rps (Hz) --- PERIOD --- s per rev mins per rev hours per rev Linear speed: m/s --- METRIC --- cm/s km/s -- IMPERIAL -- inches/second feet/second feet/minute - RECIPROCAL - min/mile min/km min/5 km min/10 km --- OTHER --- km/h mph miles/second knots furl's/f'night Mach c (light speed) Centrifugal acceleration: m/s² mm/s² km/s² cm/s² inches/s² knots/s² g   Enter either the linear speed (speed in a straight line) or the angular speed (rate of rotation) in the appropriate blue box, then enter the radius of rotation. The calc gives the related angular or linear speed, and also tells you the centrifugal force.
Choose the most appropriate units for your calculation from the menus, so you don't have to make any conversion yourself.
