Fahrenheit to Celsius Conversion Problems

 Problems : 

Question 1: Convert Fahrenheit to Celsius:
(a) 0^o F
(b) 15^o F
(c) 40^o F.
Solution:

The Fahrenheit to Celsius is given by the formula
C = (F - 32) × 59

1. (a) 0^o F = (0 - 32) × 59 = - 17.78^o C
2. (b) 15^o F = (15 - 32) × 59 = -9.45^o C
3. (c) 40^o F = (40 - 32) × 59 = 4.45^o C.

Question 2: Convert the following in to Fahrenheit:
(a) 25^o C
(b) 45^o C
(c) 100^o C.
Solution:

To convert the Celsius to Fahrenheit is given by formula F = C × 95 + 32
25^oC = 25 × 95 + 32
         = 5 × 9 + 32
         = 77^o F
45^oC = 45 × 95 + 32
        = 9 × 9 + 32
        = 113^o F
100^oC = 100 × 95 + 32
          = 20 × 9 + 32
          = 212^o F.
