People do not like change, in that sense people are conservative. Americans would benefit from going over to SI, but many don't want to change.
@tadbithuman America is metric, it just doesn't realise it.
@quixoticgeek sadly no, but we would benefit greatly from it.
@tadbithuman No. It really is. Under the hood, for all the anti metric sentiment, an inch is defined as 25.4mm
@tadbithuman Exactly. US is a metric country, it just doesn't want to admit it.
