Cold day

It was so cold this morning.

And my truck's door was partially frozen.

I often heard "Inversion" recently, it means the temperature reverse between mountain and town.

This phenomenon might affect chilly days??


In Japan we do not usually use Fahrenheit, we use Celsius.
Convert Fahrenheit into Celsius.
C=(F-32)x5/9

Why American do not use SI units?
Inch, feet, mile and so on,those are confuse me.......
