Re: More Canada ???

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Very first job I did in metric (before it came official), I came up with a size that did not make sense and checked it using Imperial & ASD to find I was out by one of those nasty zeroes. I have a couple of books from Europe and they use centimetres rather than mm used in Canada for section properties. It made sense from the point of view of all the zeroes.

We argued about that a lot. My position was that you introduce another step in the conversion process where errors can creep in, and you should do the calcs in SI units from the start.

The alternative view was that doing the calcs in Imperial then converting
allows you to do "sanity checks" more easily. One guy even claimed it was
too easy to move a decimal place when doing SI calculations and that's why we should never switch.

I did most if my design in imperial units before finally converting to metric.
