Imperial is mostly for measurements related to the body, (temperature, height/length, weight), presumably due to the amount of people who grew up with it and it's ubiquity in the American media. Pretty much every other aspect of those measurements not related to the body are done in Metric (It's -10c out, my yogurt is 750g, and it's about 5km to the store). Most room temperatures are in Celsius, or have dual options, and those that aren't are typically because we heavily use American made thermostats due to our trade connections, or it's an older model. Almost everything else uses Metric except for small exceptions like Construction which is again due to long/common use and trading with America. Everything with scientists/doctors is Metric.
