temperature conversion

Centigrade is converted to Fahrenheit by multiplying the Centigrade figure by 9, dividing by 5, and adding 32, or by multiplying the Centigrade figure by 1.8 and adding 32. Fahrenheit is converted to Centigrade by subtracting 32 from the Fahrenheit figure, multiplying by 5 and dividing by 9. In the chart below, the center figure represents the temperature one has read; the figure to the left is the conversion of that figure into Centigrade if read in Fahrenheit, while that to the right represents the conversion to Fahrenheit if read in Centigrade, e.g., the temperature 88 (Fahrenheit) converts to 31.1 C., while the temperature 88 (Centigrade) converts to 190.4 F.
