I've seen similar on the engine forums, someone buys a silencer with a 1" BSP stub then complains to the seller that it is too big as the stub measured 1¼"
Back in mid 70's I wanted a length of tube that was 1/2" dia so went to a friendly engineering merchant who supplied me with a 3" offcut. Back home I discovered it was measured by the internal size and not the outside sizeI've seen similar on the engine forums, someone buys a silencer with a 1" BSP stub then complains to the seller that it is too big as the stub measured 1¼"

I can't even remember now!
Back years ago, one of my jobs involved cutting glass. We had a builder come in with the traditional order on a bit of plasterboard for from memory about a dozen bits. I cut these, a little while later the builder was back cursing me, I had cut every bit a little bit small. He produced the bit of board & the glass & said check that, now the glass rules were crown stamped & certified & the glass was correct as far as I was concerned, so I asked for his rule. Out came a brand new Rabone Chesterman folding rule, made out of some sort of plastic instead of the traditional boxwood & I put it against our rule, it was about 3/8” too long over the 2 foot. I’ve never seen another plastic rule like that again, can only think they weren’t a great success!Par for the course...
"The thing you made is 3mm too big!!"
No...your Poundland tape measure is 3mm out over 300mm
I mentioned this before - I was involved in F35 production machinery close to 20 yrs ago (time flies!) - watching a German installation guy (in those dungeree overalls they seem to like over there) from DST using a laser level aimed at a wooden, many layer, folding rule to position bits of rather large, very expensive, machining centre. Must have worked, but it made me wonder . . .Back years ago, one of my jobs involved cutting glass.

I thinks that's exactly all what standard lights are supposed to only be capable of - hence the 21W max rating.Just this evening, I was telling one of my archery members (a retired electronics engineer) that I had changed my Touareg reversing reversing bulbs to LED, And the results were great and I could actually see where I was reversing, He honestly thought reversing lights were jut to tell other road users that you were reversing!!!
Quite so, you will notice that reversing lights have no reflectors either. They are to be seen by, not with.thinks that's exactly all what standard lights are supposed to only be capable of - hence the 21W max rating.
I used to fit a 100W fog lamp under the back bumper - swing it up and switch it off for MOT time. Very useful in the back of beyond when the navigator works out we've gone wrong for the next check-point. Now I just have a couple of 5W LEDs lamps either side of the tow bar - lights the whole front of the house up when I reverse in the drive.
