Frequency & Wavelength Converter
Convert between hertz, kilohertz, megahertz and gigahertz, or turn a frequency into a wavelength. A 100 MHz FM radio signal has a wavelength of about 3 meters.
Frequently asked questions
How do I convert frequency to wavelength?
Wavelength = wave speed ÷ frequency. For radio waves in air use the speed of light (≈ 300,000 km/s); for sound in air use ≈ 343 m/s.
