25.4 divided by 8 is within one-half
of a percent of the square-root of
ten. This is interesting to note, in
case you are a carpenter or mechanic
with poor math skills and can't
remember if you should divide or
multiply. Because if you start with
8th's of an inch or if you start with
millimeters, you can go either direction
by just multiplying or dividing by
the square-root of 10 on any
simple calculator. If the answer looks
too small in one case, you hit the
wrong button and now you are in
centimeters instead of millimeters.
This is because the reciprocal of the
square-root of ten looks the same
except the decimal point is moved
over. If you are going from millimeters
to inches and you press the wrong
multiply button instead of divide, then you
will end up close to 80ths of an inch, and
hopefully you will then either move over
the decimal place or do the problem
again by dividing instead.
I know this is very silly, but I had to
share something with you today!!!!

That is really cool fact! What is the dimension of the inch actually defined?

Hi John E. Franklin;
No it isn't silly. As always I liked it.
If it ain't broke, fix it until it is.
No great discovery was ever made without a bold guess.
