Hi all,
I have written some articles in the past and have a few ideas I would perhaps submit to the editor. However I am now re-thinking an article I could submit as I do not know which dimension system to apply, whether metric or imperial.
I have no problem with either, after spending many years dealing with both at the same time. But I get the impression that metric is the trendy young system and imperial is the old fogies yesteryear system which is deemed to be a relic of a bygone age, virtually indecypherable by the new age model engineer who prefer CNCing stuff and printed modelling methods and in general anything that is not too hard to do. So I am redesigning a submission from imperial to metric to suit but of course this all takes much more time. Am I wrong here?

My advice, if an author doesn’t know already whether metric or Imperial should be used. then the answer is metric.
I wouldn’t go so far as to condemn Imperial as a bygone relic, but it’s definitely fading away. Metric makes solid sense for anything new, and Metric is international. Only the USA, Liberia and Myanmar aren’t Metric.
Still plenty of Imperial about in the UK, but any Brit aged under 45 will likely need to have Imperial measure explained to them. Not good if it can be avoided because running two systems of measure in parallel causes endless mistakes and compatibility problems.
Supply is an issue too. It’s gradually becoming harder to source Imperial components, and they are often more expensive than metric equivalents. Metric fasteners in all shapes and sizes are common as muck, but Whitworth and BA are getting hard to find. Not so much the threads, but anything out of the ordinary like countersunk, cap, acorn, cheese, or round heads tend to be difficult or pricey. In the heyday of BSW and BSF, the full range was plentiful: not now.
There are good exceptions to going Metric in hobby space though. Such as living in the USA. Or restoring old British machinery, building models from old British plans, and projects aimed at folk with workshops full of imperial tools. Perhaps to celebrate traditional methods. Otherwise new design and anything involving CAD/CAM, 3D-printing, or repairing modern equipment is best done in Metric.
As most reasons for using Imperial are essentially backward looking, that might put newcomers off. For the same reason an older chap might balk at having to learn Metric, an youngster might run away from a weird hobby that seemed to need him to learn Imperial! To a newcomer, Imperial is an incoherent mess, full of magic numbers and illogical relationships. If an Imperial person can’t cope with 100 centimetres in a metre, imagine what a novice makes of 12 inches to the foot, and 3 feet to the yard. And that’s just the start…
