Temperature measurements: Celsius / Fahrenheit

Regarding temperature measurements, whether it is the ambient air for the weather, or boiling a liquid for example, the French measures still differ from English measures. You have to know how to convert measurements expressed in Fahrenheit to know their value in degrees Celsius.

If you want to convert from Fahrenheit degrees to Celsius degrees, here is the rule: take 32 off the Fahrenheit number and divide the result by 1.8.

100 degrees Fahrenheit - 32 = 68. 68/1.8 = 37.78 degrees Celsius!

Conversely,

30 degrees Celsius 1.8 = 54. 54 + 32 = 86 degrees Fahrenheit!
