No it isn't silly. As always I liked it.

What is the dimension of the inch actually defined?]]>http://www.mathisfunforum.com/profile.php?id=1187862012-04-15T01:30:30Zhttp://www.mathisfunforum.com/viewtopic.php?pid=210387#p21038725.4 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!!!!]]>http://www.mathisfunforum.com/profile.php?id=11082011-09-22T13:32:45Zhttp://www.mathisfunforum.com/viewtopic.php?pid=191495#p191495
