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 * √ε_r,	where c = speed of light λ = wavelength ν = frequency ε_r = 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
