I'm happy with metric generally speaking - except for Celsius when talking about ambient temperature. I will die on that hill. Freezing/boiling point of water is a ridiculous point of reference for temperature as experienced by humans.
Fahrenheit: 0 = really cold; 100 = really hot
Celsius: -17.778 = really cold; 38.333 = really hot
Not to mention that the Celsius grading is too big requiring use of tenths when discussing weather and setting a thermostat...
But hot and cold is relative. It's largely up to experience to have a feel for temperature. Eg, what temperature do you need a jacket in? In Celsius, around zero is jacket weather. What's room temperature? It's a pretty arbitrary 20ish C vs 70ish F either way.
I could just as easily say Celsius has nifty ten degree bands for weather. 0 to 10 is chilly fall weather. 10 to 20 is nice late spring weather. 20 to 30 is summer weather. 30 to 40 are the hottest summer days. 0 to -10 is mild winter. -10 to -20 are the cold winter days. -20 to -30 are the coldest days in a place like Toronto.
For outside weather, I've never seen anyone use tenths. Thermostats (for inside) in Celsius usually use half degree granularity.
I find it is hit or miss if a thermostat gives 0.5C or 1C for granularity. Even when the do have half degree increments I always just use whole degrees.
