Wavelength Calculator
This is a very simple program to write. All we need to know is the speed of light in air, which is 299,702,547 m/s, and one of the following formulas:
λ = c/f Calculates the wavelength λ for the known frequency f.
f = c/λ Calculates the frequency for the known wavelength λ.
As you can see, in both cases we simply need to divide the speed of light by the known value in order to get the unknown value.

Examples
A famous Dutch pirate radio station, back in the days when they were still broadcasting from the North Sea in AM, was called 192 because it was transmitting on 192 meters. What frequency did they broadcast on?
192 A results in a frequency of 1561 MHz.
When I was young CB radio was all the rage at 27 MHz. What is the quarter λ of that frequency?
27EEX6 A 4÷ results in a quarter λ of 2.78 meters.
