Frequency vs. Wavelength

Frequency and wavelength are related and inversely proportional. Calculating one from the other is trivial.

The mathematical equation is: $λ = c ÷ f$

However, in radio, the equation is usually simplified by converting the frequency from hertz to megahertz, and replacing the speed of light with a proportionately smaller number: $λ ≈ 300 ÷ (f MHz)$
