How to convert wavelength in centimetreses to gigahertzes
To convert wavelength in centimetreses to gigahertzes, use the reciprocal formula above: GHz = 29.9792458 ÷ value in cm (via λ = c/ν). For example, 10 cm = 2.99792458 GHz. The converter at the top applies it automatically in both directions.
Convert between electromagnetic frequency and wavelength in vacuum using λ = c/ν, where c = 299,792,458 m/s. 100 MHz corresponds to a wavelength of about 3 meters.
Frequently asked questions
