Description In Unit Out
frequency in gigahertz GHz
frequency in megahertz MHz
frequency in chilohertz kHz
frequency in hertz Hz
wavelength in meters (one cycle) lambda m
wavelength in inch (one cycle) lambda in
wavelength in foot (one cycle) lambda ft

Notes :
For these functions, the conversion between frequency and wavelength is valid for electromagnetic waves that travel at nearly the speed of light.

The acoustic waves propagate at the speed of sound which is subject to variations due to the air density in turn influenced by altitude, temperature and humidity.
