Re: Give The Rookie Some Advise
- Nope, Sorry.
This is an international standards definition, not semantics.
You refer to the 1893 standard which was superseded in 1959. It is
currently defined as "1 yard= 0.914 4 meter" which is 1 inch = 25.4 mm
*exactly*. The old definition currently applies only to U.S.
surveying measure and differs by about 2 ppm.
...excerpt... (Note the use of the word 'exact'.)
Announcement. Effective July 1, 1959, all calibrations in the U.S.
customary system of weights and measures carried out by the National
Standards will continue to be based upon metric measurement standards
and, except those for the U.S. Coast and Geodetic Survey as noted
below, will be
made in terms of the following exact equivalents and appropriate
multiples and submultiples:
1 yard= 0.914 4 meter
1 pound (avoirdupois)= 0.453 592 37 kilogram
