I'm pretty sure there are rules that mark .5mm, which is about .020',
which is only .005" more tha 1/64. Your attempt to get someone to
meet your absurd challenge of half of .3mm (.011) on a rule is as
ridiculous as having a scale reading in 128ths. Who could use such a
rule even if someone was stupid enough to make one. Besides, there
are many other ways to measure other than with a rule. None of them
have any use in woodworking. Give it a rest.
Give it a rest? Give it a rest? The OP asked why we hang on to imperial. I
replied with what is half of 5.3mm. YOU gave the answer but tried with out
success to show me a ruler with that marking. ;~) If you give up fine, you
can give it a rest. I was only asking 2 reasonable questions.
That's because NO ONE! makes a RULE in that small a graduation, in
either Imperial or Metric. They don't make it cuz no one can use it!!
There are other measuring instruments that can easily make that
measurement in metric. What don't you understand?
I see you now understand my point, the answer to why we still use fractions
of an inch originated by the OP. I have a couple of Bridge City rules that
are in 64 th graduations. Half way between those graduations is 128 ths of
an inch. That measurement is much easier to mark than 2.65 mm. Thanks for
helping me better understand why I perfer fractions of an inch over metric
measurements. Apparently you need much more sufisticated measuring devices
than a rule to measure sizes smaller than 1 mm. 1/64" is easily marked with
Leon, that is a good description of the need for finer graduations on your
metric rulers. Has nothing to do with whether metric or US measurements
are more convenient (except, what you're used to fits best, of course!).
And just what do you use them for, Leon? Measuring freeze blocks
and step stringers. I'm a machinist and seldom use them for measuring
anything, certainly not 1/128".
You have no point. You just want to argue.
I work with metric these days. Frankly, in 20 years I've never seen
anything 5.3mm called out. Nor have I seen .20866 inches. (Quick, what is
half of that?)
One of the beauties of the system is things tend to be more whole numbers
rather than 21/64 and 17/32. There is no logical reason that we could not
comfortably change and use metric other that we don't want to change. The
rest of the world manages to build some rather complex and sophisticated
machines with it and I bet we could too.
Yeah, but you're talking about changing life long habits and that's not so
easy a thing to do. The only way to realistically do anything is to teach
the young how to use metric and let the old folks consign themselves to
Not saying it can't be done, just that there may be more prudent things to
learn in the time the good old folks have left to them. :)
Exactly, being Canadian of sufficient age, I grew up based on the
Imperial system, but the change happened when I was in high school, or
was it junior high, sorry can't remember. Some things to this day are
better in imperial, others make sense in metric.
But I still by 2x4s , and 4x8s as that is what they come in.
