If it is off 14 F, then it is off by 7.778 C.
In relative degrees, 1 degree change in Celcius equals 1.8 degrees change in Farenheight.
To convert absolute Celcius to absolute Farenheight mulitply by 1.8 then add 32.
example 20.1 C X 1.8 = 36.18 + 32 = 68.18 F
To convert absolute Farenheight to absolute Celcius, subtract 32, then multiply by .55555 (remember it as 5 fives).
example 68.18 F - 32 = 36.18 X .55555 = 20.1 C
