The math
Speed of light (299,792,458 m/s) divided by frequency gives wavelength. That's it. The reason this tool exists is that doing unit conversions in your head between MHz, meters, feet, and inches while also trying to remember which ham band you're in is the kind of thing you get wrong at 2 AM.
