snippet: "When we saw a 'We the People' petition to the White House to make the US move to the metric system, we listed very sensible reasons why the US should listen: The imperial system is archaic, irrelevant, doesn't scale easily and to be honest, there are just too many damn units to keep track of. Well, the White House listened and is going to do... nothing. In their response to the petition, they basically said use the metric system if you want to."
