How it works
Convert cyclic frequency between hertz, prefixed hertz and revolutions per minute. Angular frequency in radians per second is a different quantity.
result = value × source factor / destination factor

Questions and answers
Which unit convention is used?
Convert cyclic frequency between hertz, prefixed hertz and revolutions per minute. Angular frequency in radians per second is a different quantity.
Why are some results rounded?
Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
Are my inputs sent to a server?
The calculator processes inputs in your browser. Its code does not send your values to a server.
