Frequency ‹―› Wavelength Calculator

Here is a simple JavaScript routing that converts between frequency and wavelength

Wavelength and frequency are related by the following formula:

c = λ * ν * √ε_r,

where c = speed of light
            λ = wavelength
                ν = frequency
            ε_r = relative permittivity

The following unit abbreviations are used:

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

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

Here are some familiar objects and their equivalent wavelength-related frequencies in air:

Hummer H2 (189.8 in) = 62.2 MHz
