[GreenKeys] The Metric System (was Independence Day

[Lester Veenstra]

Stocked up on Metric from McMaster. Use them exclusively for new work, and
since most parts and electronics are imported, am ready there. I hear a
whiff of "Not invented here" behind the negative talk on metric.  Now they
did follow the suggestion on paper sizes where  each is is X2 the previous.

No problems here with metric here. its the strange inch type (erratically
called imperial) that i find confusing. no idea how to read my calipers in
inch scale. threads are too coarse, head too big and then 15/32? c'mon, you
can't be serious.

And imagine that you didn't used decimal system in currency. the British
were one of the last to change to decimal counting in that.

;)

(not to mention factories inventing their own threads and sizes for
protection reasons...
