Just a question

I was listening to a US radio station on medium wave (one of my
hobbies!) last night and they were talking about temperatures being
"30 below"

I had never been quite sure what they meant by this but looking at a
weather site the temperature for the area was being given as
1F. So I presume "30 below" simply means 30 below freezing point.

Is that right?

Well done so thats +2F then

And Regina is the Provincial capital of Saskatchewan, Canada and
-40/45c is expected however -40 is minus 40 on both F/C scales
