Frequency-Wavelength Converter
For electromagnetic waves, frequency and wavelength are linked by the speed of light: wavelength equals the speed of light divided by frequency. This converter uses c = 299,792,458 m/s, the speed of light in a vacuum. For example, 2.4 GHz Wi-Fi has a wavelength of about 12.5 cm.
1 Megahertz = 299.792458 Meter
How to convert Megahertz to Meter
Megahertz and Meter are not related by a single multiplication factor, so each value is converted with the full formula rather than a fixed ratio.
- Frequency to wavelength
λ = c ÷ f - Wavelength to frequency
f = c ÷ λ
Example: 5 MHz = 59.9584916 m.
Watch out: Frequency and wavelength are inversely related, so doubling one halves the other. Inside glass or a cable, waves travel more slowly and the real wavelength is shorter.
