About these units

Short background on the units used in this conversion.

Megahertz (MHz)

The megahertz (MHz) equals one million hertz — a common unit for FM radio, amateur bands, and processor clock references.

Megahertz appears in broadcast band listings, RF engineering, and the classic AM/FM radio frequency dial.

Wavelength in Metres (m)

Wavelength in metres is a reciprocal unit: frequency in hertz equals the speed of light divided by wavelength. At 1 metre, frequency is 299,792,458 hertz.

Metre-scale wavelengths describe long-wave radio, geophysical signals, and introductory physics problems linking f and λ.
