The worst thing is (ignoring the irony of sticking to 'imperial' measures, as in old British empire measures), US imperial measures are different to imperial measures elsewhere. At least with the metric system there's no ambiguity, and it's base10 so easier to calculate, and the orders of magnitude make sense. And they also translate; a litre of water is functionally equivalent to a kilogram in weight.
