Oh ... so I&#39;m a nitpicker. I can&#39;t shake the years in the metrology labs.

Uh .... .001 of a mm (one-thousandth of a millimeter) is one micrometer (not to be confused with the measuring instrument - SI decreed it would be named "micrometer" ) or 1 um, or 1,000 nanometers, or ten A(with circle over)ngstroms.

That is equal to .000 039 37 inches - roughly 40 millionths - not a great deal, considering that the average hair is about 1500 millionths of an inch thick.

Golfers may be picky - but I don&#39;t think they are THAT picky.
