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 = GHzM = MHzk = kHzH = Hz k = kilometerm = metercm = centimetermm = mmnmi = nautical mile mi = statute mileyd = yardft = footin = inchmil = 1000ths of an inch

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

 Hummer H2 (189.8 in) = 62.2 MHz Golden Gate Bridge (6,450 ft) = 153 kHz Earth Equatorial Diameter (7,926 mi) = 23.5 Hz 0402 Surface Mount Capacitor (0.040 in) = 295 GHz Ticonderoga #2 Wooden Pencil (7.5") = 1.57 GHz Meter Stick (1 m) = 300 MHz Boeing 747-400 (231'10") = 4.24 MHz   Channel Tunnel, "Chunnel" (37 km) = 8.10 kHz
