We kept linear measurements the same (feet, yard, miles). So it's a bit of a stretch to say we're not imperial. I'd say it's "US imperial".

I was about to comment that feet, yards and miles are not imperial measure; but I checked, and WP says they are in fact imperial units. So i learned something today.
Therefore US pints are 16oz, not 20oz, and so on for most fluid measures (fluid ounces are based on dry ounces, which are avoirdupois, not imperial).
