haha! Right you are! I was writing something else at the time that had outdoor temps in C, and had a braincramp. We use both here every day. Can't we all just agree on one or the other?! GEESH!

" Can't we all just agree on one "
I won't hold my breath waiting.

I think the utility of the 3 temp scales, Fahrenheit, Celsius (centigrade for old folks) and Kelvin is their relative utility as to the range of scale... 1-100

for weather ... Fahrenheit as the temps usually run between that range 0-100

for science ... Celsius the temp difference between freezing point and boiling point of water... typical lab requirements

for physics and chemistry.. gas laws... Kelvin, as the temp scale is always a positive value
