So the youngsters are taught in metric? Yes, and they don't use it!
In electrical work we started to change to S.I. late 60's/early 70's. What a hotch pot idea!
The basic metric system is reasonable enough (although the human mind still reverts back to what you learned "x" years ago) but even in a forum such as this you find that the system is being abused. The old centimetre? How can that be used as a unit of measurement since ALL units are in powers of THREE?
So all the comments of x cm. for this or that, sorry, it's either metres or millimetres guys.
Which now makes me wonder about the use of cubic centimetres for volumes......
Oh dear, is it just me or has my grey cell gone into warp drive?
PS At the time of the changeover, busy learning to use SI, working in M.O.D. land (they were still using C.G.S.), I had been brought up on M.K.S. and was trying frantically to go into SI. No wonder my mind is a mixture of apples, oranges and whatever! Having just got the hang of SI, I went to work in one of our former colonies... Yup, they didn't want to know about metric. Back to square one.
There is (by rumour) one road in the USA that is actually calibrated in metric terms. Quite good fun driving a car with imperial gauges and trying to calculate distances / times by mental arithmetic.
