Dear John,
From your remark I think that we can safely say that you are numerate
– even highly numerate!
However, in planning a metrication program for your community (school,
work group, company, industry, or national) we probably need to plan
more carefully for the people whose numeracy is lower than yours
rather than planning for you and the few other highly numerate people.
Consider these reports at:

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.
