No, I think the question is why the metric system isn't used by default for most purposes -- like road signs.

- cassianoleal 4y agoI suspect that road signs don't use metric in the US and the UK for safety reasons. Especially speed signs. Someone who's used to thinking in miles per hour suddenly seeing a sign in km/h will likely speed up to approximately 150% of the legal limit.
