To be fair, the Fahrenheit measurement should be pretty intuitive here. Fahrenheit is easy because 0 degrees is “really fucking cold” and 100 degrees is “really fucking hot.” So anything triple-digits should be easily recognizable as “yeah that’s way too fucking hot for a phone.”

This is also why I prefer Fahrenheit to Celsius in general (even though I am an engineer and am not a die-hard patriot or anything like that). It is a more practical scale for everyday usage.
