With respect Jake et al, IMO that's just a fear of the unfamiliar....and
BTW a 4'x 8' sheet of ply is 1220mm x 2440mm.
Metric rationalisation of sheet sizes mean they are now cut to 1200mm x
2400mm so they fit in your VW (RVC) even easier...;-)
Whether you measure 4' on your tape measure or 1220mm on your metric
tape measure, it's the same thing and just as easy to read. Here in Oz
we had the foresight to convert to metric during the early 70s so I had
learned imperial measurement at school in the 60s but worked with metric
from the 70s on. I speak (and gesture) in imperial but would not ever
want to work in it ever again.
Once you understand metric measurement it is really very simple and
logical...just sometimes until you are familiar you may misplace the
decimal point.... And ask most anybody outside Nth America to show you
60cm (or preferably 600mm) with their hands and they will have no
problem.
I still talk in psi for my tyres too but the metric equivalent is kPa
(kilopascals) and it aint difficult.
30psi is a shade over 200Kpa and 40psi is close enough to 275Kpa. Easy
enough to interpolate anything in between...
Embrace and understand metric and maintain imperial measurement and
there is no need for confusion between any of us.
But I will confess, I do have one exception however where metric
measurement will never be the norm. My surfboards are 8"4" and 9'1" and
that will never change. You would look a right dick if you went to a
surfboard maker after a 2528mm or 2756mm board...:-)
My skis OTOH will always be 183cm cos 6' will never sound right...

Worse than that Kim, they use kilopascals, and I'll send you one if you
really want one! I still don't know whether the barometric pressure is
fai= r or foul!
If you think the metric system is cool, try living with the stuff. It is
completely non-intuitive and indeed was designed by the French to be
that way! A 4 x 8 sheet of plywood is theoretically 2440 x 4880 mm. No
way. If you ask someone to show you with their hands what 2 feet looks
like, most people get pretty close - ask them to show you 60 centimeters
and they're stumped. With feet and inches I can divide a foot by 1, 2,
3, 4, 6 and 12.
With metric, you can only use 1, 2, 5 and 10, making it much more
difficult to use in construction. The CBC, because it is funded by the
Canadian Government, had to convert all its scenery to metric! Cost a
lot for zero gain.
I'm surprised that I am still so pissed off that we went Metric, but
really, there is no good reason to use it in your daily life. I already
hav= e tons of wrenches in Imperial and Metric, and that's where it
should have stopped.
Sorry for the tirade. I feel calmer now.
Feet and inches, chains and rods, gallons and miles forever!
