Wavelength in meters (λ m)

Electromagnetic wavelength in vacuum, in meters. Frequency = 299,792,458 ÷ wavelength (Hz).

What is a meter of wavelength?

Symbol: λ m
Quantity: Frequency & Wavelength
Unit system: SI
Definition: Electromagnetic wavelength in vacuum, in meters. Frequency = 299,792,458 ÷ wavelength (Hz).
Exact: Yes, the value is exact by definition
Source: SI Brochure, 9th edition (BIPM, 2019)

Used for shortwave, FM and VHF radio. Amateur radio bands are often named by wavelength, such as the 2 m band.

Wavelength in meters in other units
Wavelength in meters	Megahertz	Hertz	Kilohertz
1 λ m	= 299.792458 MHz	= 299792458 Hz	= 299792.458 kHz
10 λ m	= 29.9792458 MHz	= 29979245.8 Hz	= 29979.2458 kHz
100 λ m	= 2.99792458 MHz	= 2997924.58 Hz	= 2997.92458 kHz
1000 λ m	= 0.299792458 MHz	= 299792.458 Hz	= 299.792458 kHz

The next smaller frequency & wavelength unit is the megahertz (MHz). 1 λ m = 299.792458 MHz, and 1 MHz = 299.792458 λ m.

The next larger frequency & wavelength unit is the gigahertz (GHz). 1 λ m = 0.299792458 GHz, and 1 GHz = 0.299792458 λ m.
