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?
