I tend to got with metric for small measurements and imperial for larger
same hereIts feet and MM for me, under a foot swap to MM
I was glad to see the back of pounds, shillings & pence while I was at school, metric (decimal) money with base 10 was much easier to work with.
+1I really dislike when people mix cm/mm. It's 5cmx300mm!
we could start using poles, chains, furlongs and perch again if were not careful
I remember the tables of obscure measurements printed on the back of exercise books at school in the 60's
I see length and weight in inches.I find it easier to think in inches. A system which worked for hundreds of years.
Funny though, metric bearings, imperial sized balls inside.
I think Italy was still using miles until fairly recently. Well before WW2 anyway.Learnt metric at school,used metric for everything ever since.
But during the years both working and hobby, watching YouTube videos and now as a machinist I'm still learning imperial.
Sometimes happens to find a 13mm bolt which doesn't fits tight to the spanner and then I know it's not 13mm but 12.7mm or 0.50" or better 1/2" , and things like that .
Problem with inches especially doing machining in a country where most people doesn't even know what we are talking about...
Is that there are various inches
1" as we call mechanic inches is 25.4mm
1" pipe is 32mm
1" tubing is if memory serves well 25.4mm inner diameter or it was 32mm inner diameter
Threads? There are already a lot in metric system
Then we have SAE UNF,SAE UNC, WHITWORTH , BSPT, BST, NPT,plus all the variations of thread pitch shapes as well as for metrics
There's to become mad honesty .
About the thousands, I can get the point but I can't visualise it yet if not metric.
We don't say 0.1mm we say 1/10 ,0.01 1/100 ,0.001 1/1000 of mm .
So I can get why it's called thousand but it's way way bigger than my thousand meaning.
I don't know if you can get the point.
If you don't use them everyday of your life you can't figure out immediately what for example 10 thousands of an inch is (0.254mm)
