I’ve never really understood it. My Mom asks me to check her pool’s temperature. “24 degrees”
And she’s confused! “I have no idea what that means! Tell me in normal pool temperature”
But if I told her the outside temperature in Fahrenheit she’d be utterly confused, as would I. Only thing I know about Fahrenheit is that 30 is cold and 100 is very hot.
The pool thing is completely crazy.
I can understand the oven thing though. It’s so hot that it might as well have nothing to do with other everyday temperatures. So if you get ovens and recipes from the United States, I can see why it wouldn’t really be a problem. It’s treated as basically just a power level.
Still I wish we all switched to Celsius. It just feels useful to me to know how far you are from the boiling point of water, for instance.

Construction materials, imperial.
People’s weights, pounds, although most people understand kilos, they’ll just internally think you’re being a hipster if you make them convert in their head.
People’s heights, generally feet. They’re hard to convert back and forth to cm, so people are often confused when I use cm. Though on government ID it’s cm.
Short distances? Mostly imperial, especially with older people, but sometimes metric.
Long distances? Hours by car. If you press it, people will use kilometers, but hours are absolutely the casual unit of distance.
Weight of things? Usually metric, but a pound of butter is a pound of butter.
Volumes? Metric, or metric-ified imperial units, like metric cups (250 ml), tablespoons (15 ml) and teaspoons (5 ml). Ounces only used for alcoholic drinks AFAIK. No one I know understands wtf a “15 ounce drink” means, even though restaurant chains sometimes use the measurement on their menus.
In Quebec in particular, pint and gallon have been completely denatured from volume units to container types. A pint is a small container, usually a carton, containing 1 or 2 liters. Usually only used for milk. Can also be a 1-litre plastic bag of milk. (Used to be a popular Canadian staple; now cartons are the more popular thing.) A gallon is a jug or jerrycan. People are aware they’re supposed to be volume units but you rarely see them used as such.
