  # 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 * √εr, where  c = speed of light            λ = wavelength                ν = frequency            εr = relative permittivity G = GHzM = MHzk = kHzH = Hz k = kilometerm = metercm = centimetermm = mmnmi = nautical milemi = statute mile yd = yardft = footin = inchmil = 1000ths of an inch
 Frequency GHz MHz kHz Hz Wavelength Relative Dielectric Constant Wavelength km m cm mm mi nmi yd ft in mil Frequency

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    About RF Cafe Copyright: 1996 - 2024Webmaster:    Kirt Blattenberger,    BSEE - KB3UON RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer.
