To convert degrees Fahrenheit (ºF) to degrees Celsius/Centrigrade (ºC), use the following formula:

Fahrenheit number - 32	x 5
9

Example:	68ºF - 32	x 5 = 20ºC
	9

To convert degrees Celsius/Centrigrade (ºC) to degrees Fahrenheit (ºF), use the following formula:

Celsius/Centrigrade number x 9	+32
5

Example:	20ºC x 9	+ 32 = 68ºF
	5
