Did you know that -40C and -40F are equal, identical, and equivalent???

And just as cold as each other!?!?

I didn’t. Till I looked it up.

I knew that!
But then I am a Canuck and work outside in the cold, so I pay attention. I grew up with Fahrenheit and missed the transition in grade school because I living in Europe as an Air Force brat. I've had to deal with both systems, so I learned the minus 40 thing out of curiosity.
