Nobody talks about "threepenny bits", "tanners" or "shillings" anymore because they were all done away with in one fell swoop in 1971 during decinalisation.
If the same principle was applied to getting rid of imperial measurements, there would be no confusion because nobody would be using, or referring to, imperial measurements. Only metric units would be used. ----- Original Message ----- From: Stephen Humphreys To: U.S. Metric Association Sent: Tuesday, October 06, 2009 9:06 PM Subject: [USMA:45942] Re: teaching customary units I would advocate making science classes metric only - however I would support having imperial in Maths and English. Don't forget that measures do make up part of the language and denying a new generation while the 'one above' converses freely using a mix of measures would leave kids confused. Nothing pro-imperial or anything - just common sense because kids would have many questions unanswered by school. I suspect that is the reason why imperial made a return to the curriculum in the UK from the 90's (when I was at school in the 80's I can't remember being taught any imperial, although I can imagine teachers 'spoke it' so to speak). ------------------------------------------------------------------------------ From: [email protected] Subject: [USMA:45941] Re: teaching customary units Date: Tue, 6 Oct 2009 12:14:29 -0400 To: [email protected] On Oct 5 , at 1:20 PM, Robert H.
