If you are you refering to temperature scales Celcius and Fahrenheit, then the crossing of the two scales happens at -40 degrees.

That is because of a 32 degree difference at freezing point of water and the F-scale is 5/9ths of the C-scale.

C = (F - 32) * 5/9

and

F = (C * 9/5) + 32

so

-40 = (-40 * 9/5) + 32 = -40
