"DEEP WRONG" is assuming everyone around the world has access to metric
equipment and material. Canada has gone metric for decades now, but there
are still things that are dealt with in Imperial units. The world is NOT
metric, Europe may be metric as well as other countries, but THE WORLD is an
exaggeration.
The paper I use is in letter format, 8 1/2" x 11". Trying to relate metric
measurements to the paper format is ridiculous. All the components I use
have footprints in thousands of an inch, why should I follow the flock for
the mere sake of following? I use metic where metric makes sense, and I use
imperial where imperial makes sense. Over here, using metric in PCB-making
is a waste of time.
I grew up with fractions of an inch and I still can't visualize 17/32" or
25/64". I've started playing with thousands of an inch since I started
using QCAD and I love it. It took a while to get used to it, but it was
worth it.
"...and please keep off terms like ounces, pints and the like..."
