Frequency, period & wavelength reference

Convert the same frequency into common units, its period, and wavelength for a selected propagation speed.

Convert frequency units

Convert Hz, kHz, MHz, GHz, revolutions per second, and revolutions per minute. Hertz means cycles per second, so 60 rpm corresponds to 1 Hz when one revolution is one cycle.

Cycle interpretation

The rpm/rps relationship assumes one counted cycle per revolution. Mechanical systems with multiple events per revolution may need an additional factor.
