I wish the US would make up it's mind about what system it wants to be on. As it stands right now you buy milk by the gallon, soda by the liter, I tell my parents it was 20 degrees and they think it must have been a nice day. Plus division by 12, and 16 is a PITA.
Anything scientific in the US has been on the metric system for 20 years or more. They should do what the UK did and keep the speed signs in miles but convert everything else.
