Metric is definately good for doing calculations. It's a lot easier to remember things in denominations of 10 instead of 5280 ft per mile or 4 quarts per gallon. When doing homework in imperial, things can get a bit messy.

One thing that I do prefer in imperial is temperatures. The much wider range seems to give a better representation of temperature than celcius does. But then, since I am American, I am biased on that.

There is one imperial measurement that pisses engineers (or at least the ones I talk to) off the most, and that is the slug. Nobody knows why they made it or exactly what it is in terms of measurements due to the arbitrary conversion of 32 lbs = 1 slug. I blame Arthur Mason Worthington (according to wikipedia) for making this stupid measurement in 1902.

Oh yeah, and don't get me started on the distinction between pound-mass and pound-force...
