Inch to mm conversion table
« on: 28.02. 2019 20:25 »
I have made a conversion table that I printed and hung up on the shed wall.
Has been useful a couple of times as I don't always have my phone at hand to use a converter app or look it up on the net.
Please feel free to download it for your own use.
The .xls document can be opened with free downloadable Apache open office software if you don't have Microsoft Office

 Probably what I use use most (of probably anything other than beer) is the conversion table in the back of my Haynes manuals- photocopied those too

40+ years in a machine shop..... First year apprentice and using imperial, then out on the shop floor, many years working in imperial, new designs come along and are metric conversions of imperial, now it's 100% metric..
1 inch o ring recess became a 25.4mm o ring recess, still buying them today instead of 25mm ones.
British company taken over by a German one.

G'day morris.
Thanks for posting that.
I was lucky enough to have been taught both imperial and metric. I'll go to a hardware and ask for a 6mm x 1mm pitch bolt 3-1/2 inches long then tell the young pimple face that 90mm will do When drilling a clearance hole but don't want a 64th I go for a close metric.
Cheers

Indeed. Apprenticed all the way through the mid/back end of the 70s. Metric drawings, imperial machine tools. Still think in thou.
