The point is that they chose exactly the wrong value, since, for making a
quick & approximate conversion, you must remember that -40 C = -40 F
and that 1 Celsius degree is more or less 2+ 1/10 Fahrenheit.
So 100 F = -40 F + 140 F
140 F = 70 + 7 C
-40 C + 77 C = 37 C (actually 38).
So what? It's not a scientific chart, it's just a graphic art.
