As a Canadian with a living memory of when we made the switch here, I feel your pain. Though to be fair, I was a child at the time and so probably had an easier time of it? But in some ways, I'm still transitioning to this day!

Take temperature, for example. When Canada went metric, all the weather reports switched to Celsius but our indoor thermometers and thermostat were still in Fahrenheit. So I wound up in a situation in which outdoor extreme temperatures became more relatable in C, while typical indoor temperature ranges sounded better in F. I particularly liked winter temperatures in C. It was so intuitive that < 0 means snow and > 0 means rain.

Today, I am more comfortable with C for indoors as well, but not for cooking. I guess that's because a lot of recipes still say set the oven to 350 or check the meat on the grill is at least 160?
