Frequency

Disclaimer: This calculator has been tested and is believed to be accurate to 6 significant figures. User assumes all risks for its use.

Here is a simple JavaScript routine that converts between frequency and wavelength in the electromagnetic field realm. Wavelength and frequency are related by the following formula:

c = λ * ν * √εr

where  c = speed of light

            λ = wavelength

            ν = frequency

            εr = relative permittivity

Frequency Units Wavelength Units
G = GHz

M = MHz

k = kHz

H = Hz

k = kilometer

m = meter

cm = centimeter

mm = mm

nmi = nautical mile

mi = statute mile

yd = yard

ft = foot

in = inch

mil = 1000ths of an inch

A table of calculated values can be found here: Frequency - Wavelength Conversion Table
