Hi there -

To convert Celsius to Fahrenheit, multiply by 9/5 and add 32:

C = 5/9(F-32)   or   C = F - 32/1.8

Example:  Convert 40 degrees Celsius to Fahrenheit:

40 x 9 = 360   360 / 5 = 72   72 + 32 = 104

A weather forecast of 40 degrees Celsius or 104 degrees
Fahrenheit is too hot for comfort!

To convert Fahrenheit to Celsius, subtract 32 and multiply by 5/9:

F = 9/5C + 32   or    F = (C x 1.8) + 32

Example:  Convert 98.6 degrees Fahrenheit to Celsius:

98.6 - 32 = 66.6    66.6 x 5 = 333   333/9 = 37

"Normal" human body temperature is 98.6 degrees Fahrenheit,
37 degrees Celsius.
