Quick Celsius breakdown from a Canadian:

40+ - most Canadians stop eating food and hope for a quick death 35 - you might just be able to live with this if you do nothing at all 28 - right about the place where comfort gives way to a general sense of warmth, something that makes any Canadian uncomfortable 23 - room temperature, and why “room temperature IQ” is an insult only Americans could have come up with because their scale was made by a madman 15 - If it’s Autumn you are wearing a light jacket, if it’s Spring you are sweating 5 - sweater time 0 to -10 - that stereotypical TV winter experience, where everyone is skating and sipping hot chocolate? Yeah that’s like half the year here. You better like hot chocolate. -15 - We enjoy the fresh air, others will probably find it painful to breathe directly; put on a scarf! Do not brush your teeth immediately before going outside unless you want to experience mint-flavoured pain. -20 - Canadians put their boots on by now. Exposed skin on a windy day can get frostbite in as little as 10 minutes. -30 - We will debate putting a coat on to put the garbage out at this temperature, usually erring on the side of caution in case your kids lock you outside again. Seriously invest in good winter gear for this, this temperature can kill surprisingly fast and it only gets increasingly unpleasant from here. -40 - turns out you can’t form snowballs in hell because the snow is too crispy
