.....They are perfect as they are and need no changing.....I am NOT for disturbing the SI or the 'metric system' BUT for bridging the gaps left by ORIGINAL authors of *metric reform* delibrately or otherwise. The fact 'knots, nautical mile' and the 60 minute HOUR are tied in a way that DOES not allow *METRE to be linked to Time* has been my observation.
This make me and my contribution a POSITIVE contribution for bridging the gaps left by early authors to *LINK and tie the base units for Time and Length* via Decimalised HOUR when related to Decimalised arcAngle - moreso NOT affecting the 360-degree circle and/or the trigonometric functions or the 90-degree quadrant.THE PRESENT SI-METRIC UNITS suffer since NOT related to Metre(m) -the unit for length with the Time unit - second(s).
My submission, thus: *SI-METRIC SYSTEM IS THE ONE THAT BRIDGES LENGTH UNIT - METRE (m) with TIME UNIT (s). Anything that cannot be related to Metre, is therefor non-Metric and hence non-SI*.
Be kind to send me your comments 'without reference like usma 31768' for the list may not be interested in automatic discussion involving Time - that I talk.

I just checked the definition of the metre:
Le m�tre est la longueur du trajet parcouru dans le vide par la lumi�re pendant une dur�e de 1/299 792 458 de seconde.
That comes from: http://www1.bipm.org/fr/si/base_units/
There is nothing in that definition tied in any way, shape or form to the radius of the earth. I do not understand this need to redefine the metre just so there is a nice rounded number metres to define the radius. We are promoting the existing SI as it stands. This type of activity was the death knoll for FFU. People over time not satisfied with the standard unit length took it upon themselves to come up with their own definitions, thus corrupting the ancient units into a really big mess.
If you want to tinker with changing definitions of units, do so, but with the old obsolete units. Define a new nautical foot, yard, mile, whatever, but leave the SI units be. They are perfect as they are and need no changing.
The presnt metric system is used in all countries and by 97 % of the people of the world. The metric system establishes and maintains prosperity in first world countries and brings growth and modernisation to the third world. Changing this perfect balance would be a disaster worse then a million tsunamis.

Pat, sir & friends:
I see nothing rong in re-establishing the Mean Radius of Earth via GEOID 'arcuser' concept. The document measures Earth Radius at Lat.45*=6367.473 km & Mean Radius=6371.146km.
In my work:
Shelving Mile in Favour of Nautical Kilometre; Proceedings of 3rd International Conference on Metrology In New Millennium And Global Trade (MMGT - 2001); Document # 27; pp.169; National Physical Laboratory, New Delhi; 2001 February 4-8;
I use the Earth as a 'hypothetical sphere Radius of 6371km' to arrive at the lenth of New Metre (m')
as:1/10^5th of 1* 'arc-angle' at Earth centre. This takes care of necessary corrections that may be needed while defining length of *New Metre (m'); Nautical Kilometre and new 'Time interval' decimal second (sd) as: 36% of SI-atomic second* linked to duration of the Year 2000.
This post is NOT intended to raise 'Metric/Decimal Time controversy BUT to resolve the issue'.

Dear All,
Since the metre was initially based on the size of the Earth, you may be interested in modern methods of Earth measurement. See:
http://www.esri.com/news/arcuser/0703/geoid1of3.html
Particularly interesting to me was the SPHEROID DEM at the bottom of page 2
of this 3 page document.
Cheers,
