This is not quite right.

The scientific formulas are:
    C to F:  (Cdeg * 9/5) +32 = Fdeg
    F to C:  (Fdeg -32) * 5/9 - Cdeg

        Ex: 100C * 9/5 = 180 + 32 = 212F  (boiling point H20)

For quick calculations the estimating formula (discussed in the Tues 
Meeting) is:
    C to F:  (Cdeg * 2) + 30  = approx Fdeg
    F to C:  (Fdeg -30 ) / 2  = approx Cdeg


ex. 17 C
     exact:    17 * 9/5 + 32 = 62.6
     approx:   17 * 2  + 30= 64
