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 
Here are some familiar objects and their equivalent wavelengthrelated frequencies in air:
