The Imperial system is still used in many places.
The height of planes flying or top of mountains are usually in feet instead of meters. Also the height of buildings. It's easier visually for me to look at height of building in feet instead of meters.
Also, body temperature is also in farhenheit instead of celcius in most cases.
Besides that, I think everything else is in metric system
One area where I remain in the imperial world is a persons height and weight. If they issue an APB and describe the person in cm and kg I wouldn't know this person if they were standing next to me (I don't know my own weight and height in metric).
