If it were not for the federal government I doubt you would have an interstate highway system or even a standard imperial inch/gallon for that matter. If it were up to the states you wouldn't have a standard size of roads, pipes or even windows.

The US doesn't use imperial. The gallon is hard proof of that.

It is called imperial in Autocad but it is not british imperial because british imperial is different from american imperial.

We use "customary" weights and measures, as there is no one source from which they all derive prior to being formalized.
