The US does use metric system (you can easily go and buy 2 liter bottle of Coke). What you probably mean, why the metric system is not mandated as the only one acceptable for basically everything? Why indeed.
- mcherm 4y agoNo, 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.
- timbit42 4y agoCanada had both numbers. The kph was on top and larger. The mph was below and smaller, obviously. Now the mph has been removed for quite some time.
- anotherevan 4y agoJudging by your popular media, you only use metric in science fiction shows where the distances between spaceships is so big the number is effectively meaningless. Occasionally hear grams for small amounts. That's it.
