Instructions

1

Multiply the Celsius temperature times 9. Example: 56 x 9 = 504
2

Divide the product by 5. Example: 504/5 = 100.8
3

Add 32 to the quotient. Example: 100.8 + 32 = 132.8
4

Another way to convert Celsius to Fahrenheit is:

(C + 40) * (9/5) - 40 = F

And there you have it. That is how you convert Celsius to Fahrenheit.
5

In order to convert Fahrenheit to Celsius one only has to change the dividend and divisor to 5/9.

Example F - 32 * 5/9 = C

Example F + 40 * 5/9 - 40 = C
