Question

The localist meteorologist is converting temperatures from Celsius to Fahrenheit. She knows that the formula for the conversion from Fahrenheit to Celsius is C= 5/9 (F - 32). What would be the formula for converting to F from C.

Answer 1

Start with C= 5/9 (F - 32) and solve this for F in terms of C:

9C = 5(F - 32). We want F alone, so div. both sides of this eqn by 5, obtaining

9C

---- = F - 32. Now add 32 to both sides:

5

9C 9C + 160

----- + 32 = F, or --------------- = F

5
