How do you make a Fahrenheit sign in Excel?

Celsius = (Fahrenheit -32) * 5 /9

So you get the Fahrenheit and subtract 32. Then multiply the result by 5 and then divide by 9.

To put that into an Excel Formula, we could assume that the Fahrenheit value is in A2. Then you would put the following formula into another cell:

=(A2 - 32) * 5 / 9
