I've just made a couple of jigs for a project I'm working on, involving cutting
sheets of heavy card to precision of less than 1 mm (actually, nearer 0.2 to
0.4 mm). The jigs were made out of hardwood. Everything was done in metric
or course, but I just don't even know how I'd even begin to get such precision
using inches and fractions thereof, especially in getting the jig edges lined
up to the exact point of precision. Bear in mind I had no mircrometers or any
other such precision tools - just a good metric steel edged ruler, a sharp
pencil, a reasonably steady hand and an X-acto knife. Metric made it simple.

I have an all-millimeter tape measure too. It was given to me as a gift when
some people from the Russian railways came to visit us at work a while ago. It
has a Cyrillic label on the front, and a button that keeps the tape from
rewinding unless you push it. The word on that button on this Russian tape
measure is "PUSH".

I have an all-millimeter tape measure from New Zealand. It is my favorite
tape measure of all. Darn it for being so hard for us in the U. S. to get to
the point of measuring so logically and efficiently! It is worth the fight fir
us to reach the goal.

School teaches us to be really good at sliding decimal points around. I
don't find that a problem at all. What I do find to be a problem is restarting
the 1-99 numbering after each meter mark. If foot markings are that way, one
is always close enough to read. I may be 0.5 m away from the nearest integer
meter mark, and it can be a problem to get the most significant digit correct.
The other minor problem on dual tapes is that the metric scale is always on
the bottom. That is a bit clumsy for the way I mark things off.
Seriously, I don't think I have ever seen a ruler or tape direct reading in
millimeters. The numbers are ALWAYS centimeters with 10 millimeter hash marks
in between (5th larger). You have to add trailing zero, then the millimeter
marks mentally. But I don't see it as much of a problem.

Dear John,
And, sadly, millimetre only tapes and rules are even more rare. See

I haven't gotten around to blogging it yet, but I recently got some for
some home project work:

Metric drill bits are fairly easy to come by on Amazon.
