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 * √εr,

where  c = speed of light
            λ = wavelength
                ν = frequency
            εr = 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

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
