I was taught both systems at school more than fifty years ago so I'll
happily work in either or both at the same time, however my preference
is for Imperial. Being based on features of the body and the landscape
around us it somehow seems more natural and comes more readily to mind.
As with Cliff, comfortable in both systems from long use (ever so long :( )
I tend now to work in the metric system but hold extensive tooling in both
If something was originally made to Imperial measurements it seems only
sensible to continue thus, and vice versa
I was amused to buy a piece of board the other day, and to see that
it was still cut according to Imperial measurements, 4' x 4', but sold
in Metric dimensions, mms x mms. The Imperial measurement is so much
more useable, to me, using single digits as opposed to 4 digits for
I use whichever seems more natural for the job but predominantly use
metric these days. I grew up in the US so practical stuff like machining
woodwork etc was inch but all science in the US has been SI metric since
the 1960s IIRC so was used to that as well in the US. When I came back
to the UK I would mainly use imperial but have slowly switched to more

A little different perspective over here in the U.S. where I use
mostly decimal inch stuff. But sincs metric is so common the rest of
the world and a lot of stuff I make is designed for international
markets I use metric a lot. It used to be I would always be converting
in my head to inch dimensions to get an idea of, roughly, of the size
of a part. But I have been using metric so much it is now starting to
become second nature. Metrification of the U.S. is surely going to
come about because of goods made for the international market and
goods shipped here from the rest of the world. The only metric system
I can't seem to get used to is degrees C. I take showers here with 100
degree water and 40 degrees here is cold.

I left the US in 1982 and can't recall seeing metric fasteners at all in
the local places but from what I have read subsequently metric is quite
common now, most likely as you say due to so much being made abroad and
possibly also US goods being made for a world market where inch wouldn't
be very readily accepted.
Any parts that I do that go into machines that are considered "High
Tech" will be metric today. Often I will get drawings with dimensions
that look strange. This is because the part was designed in metric and
then the dimensions are converted to inch. I always check these
drawings to look for conversion mistakes because it is common for them
to occur. I wish everything would just be made metric. Since I always
work in decimal inches working in metric is no different except for
the metric (I meant that pun) being used. Meter versus foot.
