Here's a much simpler method for those not keen on algebraic equations. For a good approximate:
To convert centigrade to Fahrenheit: simply double the degrees in C, and add 30 .
for example 20deg C is app equal to 40 plus 30= 70 def F
To convert Fahrenheit to Centigrade: simply subtract (minus, or take away) 30 from degrees in F, and half it
for example: 70 deg F i.e 70-30 = 40, divide 40 by 2 ( or half that amount) = 20 deg C
