I didn't know the imperial system was named "standard". Funny, cause its everything but standard both internationally and its definitions (which are not standard as based on SI)
Claiming something isn't standard because it isn't based on SI is entirely circular in the case of weights and measures.
That said I wish the US would bite the bullet and make the switch. Mandating dual labeling on everything would be a great start. Then in 20 years we could narrow it back down to one.
