How to convert megahertz to meters of wavelength

To convert megahertz to meters of wavelength, divide 299.792458 by the number of megahertz.

Formula

λ m = 299.792458 ÷ MHz

Examples

5 MHz = 299.792458 ÷ 5 = 59.9584916 λ m
25 MHz = 299.792458 ÷ 25 = 11.99169832 λ m
100 MHz = 299.792458 ÷ 100 = 2.99792458 λ m
