Frequency  ‹―›  Wavelength Calculator

Here is a simple JavaScript routing that converts between frequency and wavelength. Wavelength and frequency are related by the following formula:

Equation Frequency Units Wavelength Units
c = λ * ν * √εr, where  c = speed of light
            λ = wavelength
                ν = frequency
            εr = relative permittivity
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
