Unfortunately, the conversion is not that simple. Currently switching between the unit systems changes the absolute value of the temperature, i.e. it thinks 5C = 5F.

A bit more work has to be done to get this conversion working, because it is different from all the other conversions we have so far.

Also there is a missing white space.

I think Kelvin should also be the base unit in imperial? Something like color temperature you would still want to see as Kelvin even if you use imperial length units.
