You had a mistake to calculate the temperature for conversion.
*A certain temperature : C = 5/9 (F - 32) or F = 9/5 C + 32
**Delta Temperature : C = 5/9 F, F = 9/5 C
In your case, you have to apply (**), not (*).
Please find a presentation material for "Reiterative Mistakes in Simple Engineering Work" attached. It was for our company`s engineers and only selected the temperature conversion part.
