We of all people should have our metric to Imperial conversions sorted out.
Last time I checked, 1"=25.4mm. Hence, 0.5mm = approximately 0.020" Since your conversion of 0.005" to 0.13mm is correct to two figures, I assume there was a glitch somewhere in your conversion 0.5mm to inches. Don't worry, it happens to the best of us.
Sort of off-topic, but WTH: ... in collegial defence of SixtyFiver:
In the 80's, I was one of two or three Vancouver, Kitsilano neigbourhood automotive jobbers working in an old garage keeping the neigbours' motorcycles and cars alive while the weasels and rich were reaping, and the rest of us were losing traction. I still have my instruments that measure 'Imperial', even though Canada was long ways into metric. The pro tool wholesalers were still distributing conversion cards for everything. If SixtyFiver is still using the old Imperial, I can understand why. You just stick to what you think in. I am still using a psi tire-gauge instead of one in
thingy-puffer-Pascals, even though I live in metric Japan. Conversely, I think I've forgotten how to think in
thou' measures.
Why did I ship drawers full of a useless fortune in fractional spanners and sockets all the way across the Pacific.
Sigh! — I dunno. I did gave-away all my BSA and BSF hardware to a friend who restores ancient Vincent motorcycles. Yep ... some of us on C&V are that old. Ancient Brit tools were used to work on a Triton road-racer way back in the days when my balls were bigger than my brain. (Age seems to mercifully reverse this condition.) Those relics might have been useful to work on ancient Brit bikes, but I don't have any. I may still have a couple of spanners Dad used on his Bates
All in good fun — on with the show. Antiquarianism is where a lot of us are at anyway.
I am gratefully enjoying all the comments so far —
grazia tante!
