Adjustable wrenches are a bad idea imho. They strip bolts very easily. It is best to standardize on a few bolt sizes and avoid them all togethor. We use Imperial measurements with a little bit of metric mixed in. The reason we use Imperial is because most materials are in that system, making it easier to work with. Its pretty rare to have to do unit conversion on the robot anyway. Foot to Inches is pretty easy, and thats the only I can think of you might need. When you get into volume measurements is when the Imperial system falls flat.
