Well, I'm impressed! From "I honestly don't even know how to start them"
to a dispatch table containing first class functions made with lambda in
under 9 hours. Well done!
I expected you to start with a big block of if...elif statements, but a
dispatch table is a much nicer solution.

You tell us :-) Does it work? Are you confident that the conversion
equations are correct? If you try converting various temperatures, do you
get the right results?
