so 14C° X 1.8 ==> 25.2F°
and 8C° x 1.8 ==> 14.4F°

When you speak of tolerances, they are simply a unit conversion. There is no 'zero' to reference. Merely the difference between Celsius and Fahrenheit graduations.

One of my thermodynamics instructors from college would have re-written your note thus...
Note how the letter and the degree symbol are flipped when the temperatures are relative. This affects your math.

plus or minus 14 Celcius degrees
so if you have a temperature requirement and tolerance it would be"
x°C ±yC°, which would be read"
x degress Celsius plus or minus y Celcius degrees

However you point about academia is well taken. Once had to do a heat transfer on a 2x4 wall, asked the professor what dimension we should use for the 2x4. He looked at me like I had lost my mind, “why, 2” by 4” of course, why do you ask” was his reply. When I told him that today a 2x4 actually measures 1.5” & 3.5” he was flabbergasted.
RE: Wow- Interesting- CONVERSION
I have not done a lot of thermo analysis. My experience has been that if I were to use 4" as the depth of a 2×4, that would be the most accurate number in my calculation.
A few years ago, I designed the back steps for my house. I referred to one of my college mechanics of materials text for lumber sizes, and I got 1-5/8 by 3-5/8". You know you are getting old when...

RE: Wow- Interesting- CONVERSION
I have not seen this notation in any texts either. My thermo instructor wanted to distinguish between a temperature of 86°F and a temperature increase of 16F°. This does affect how you do your conversions.
He was British. Does that help?

Of course, rarely did °F and in school °C was rare, it was usually Kelvin.
