I was more thinking of when you're telling your friend what the temperature is outside, or scenarios similar to that. It's not useful in most other applications.
What difference does it make if the temperature is 79 or 80 F? That's a difference of about half a Celsius, and as a Celsius user, I can tell you that I don't plan my daily life based on a half a degree difference, or even a one degree difference; 5 degree precision is almost always enough.
Agreed, though if you are measuring it via instrument then what difference does it make how "round" the number is?
