Measured in Kelvins I think, which makes about as much sense to me as measuring wind speeds in suction power or something.

"Measured in Kelvins I think, which makes about as much sense to me as measuring wind speeds in suction power or something."

Kelvin temperatures start at absolute zero. There are no negative Kelvin temperatures.

But with temperatures hot enough to make things glow with heat, you're pretty far above "normal" anyway. The freezing point of water is at 273^o Kelvin. A warm glow is somewhere around 2700 degrees Kelvin.
