jumpy - here is the conversion:
To convert a Fahrenheit temperature into Celsius:
Tc = (5/9)*(Tf-32)
For example, to convert a Fahrenheit temperature of 98.6 degrees into degrees Celsius first subtract 32 from the Fahrenheit temperature to get 66.6. Then you multiply 66.6 by five-ninths to get 37 degrees Celsius.
To convert a Celsius temperature into degrees Fahrenheit:
Tf = ((9/5)*Tc)+32
For example, to convert a Celsius temperature of 100 degrees into degrees Fahrenheit, first multiply the Celsius temperature reading by nine-fifths to get 180. Then add 32 to 180 and get 212 degrees Fahrenheit.
Hope this helps!
