 Metre   (Site not responding. Last check: 2007-10-26)
In the 1870s and in light of modern precision, a series of international conferences were held to devise new metric standards.
The Treaty of the Metre (1875) mandated the establishment of a permanent International Bureau of Weights and Measures (BIPM: Bureau International des Poids et Mesures) to be located in Sèvres, France.
However, the International Prototype Metre remained the standard until 1960, when the eleventh General Conference on Weights and Measures (CGPM: Conférence Générale des Poids et Mesures) defined the metre in the new SI system as equal to 1,650,763.73 wavelengths of the orange-red emission line in the spectrum of the krypton-86 atom in a vacuum.

 Measurement
The 17th General Conference on Weights and Measures in 1983 defined the meter as that distance that makes the speed of light in a vacuum equal to exactly 299 792 458 meters per second.
The speed of light in a vacuum, c, is one of the fundamental constants of nature.
In 1967 the General Conference on Weights and Measures defined the temperature of the triple point of water (the temperature at which water exists simultaneously in the gaseous, liquid, and solid states) to be exactly 273.16 kelvins.

The International Committee for Weights and Measures is the English name of the Comité international des poids et mesures (CIPM, sometimes written in English Comité International des Poids et Mesures).
Its principal task is to ensure world-wide uniformity in units of measurement and it does this by direct action or by submitting proposals to the General Conference on Weights and Measures (CGPM, Conférence générale des poids et mesures).
The CIPM meets annually at the International Bureau of Weights and Measures (BIPM, Bureau international des poids et mesures), and discusses reports presented to it by its Consultative Committees.

A definition of TAI was approved by the Comite International des Poids et Mesures in 1970, and recognised by the Conférence Générale des Poids et Mesures in 1971.
TAI was established by the Bureau International de l’Heure as a time reference co-ordinate, and was calculated on the basis of the readings of atomic clocks operating in various establishments in accordance with the definition of the second.

Rather than continually choosing more stable transitions, the Bureau International des Poids et Mesuresdecided to fix c, thereby shifting any uncertainty in its value to the definition of a meter.
At the Conference Generale des Poids et Mesures, the speed of light was defined as exactly 299,792,498 meters per second.
Conference delegates also redefined the SI unit of the meter, without changing its value, based on this set quantity.

 The Time
Before even the ephemeris second was defined, the second (not “SI” because this is before SI) was defined as the fraction 1/86400 of the mean solar day (this is, after all, the historical definition of the second, the day being divided in 24 hours of 60 minutes of 60 seconds each).
TAI is maintained by the Bureau International des Poids et Mesures which periodically averages various atomic clocks around the world to compute TAI, and publishes the offsets of the various clocks to TAI (the master clock of the Observatoire de Paris is used to centralize the offset computation).
It is kept in a vault at the the Bureau International des Poids et Mesures in Sèvres, France.

The basis of the measurement of time on the Earth is International Atomic Time (TAI) which is made available by the dissemination of corrections to be added to the readings of national time scales and clocks.
The time scale TAI was defined by the 59th session of the Comité International des Poids et Mesures (1970) and approved by the 14th Conférence Générale des Poids et Mesures (1971) as a realized time scale.
As the errors in the realization of TAI are not always negligible, it has been found necessary to define an ideal form of TAI, apart from the 32.184s offset, now designated Terrestrial Time, TT.

The International System of Units, or SI (from its French name Système international d'unités) is a system of metric weights and measures that was adopted by the General Conference on Weights and Measures (CGPM or Conférence générale des poids et mesures) in 1960.
The SI is maintained by the International Bureau of Weights and Measures (BIPM or Bureau International des poids et mesures) and may be updated by the CGPM.
Although the IEC is the organization that provided the international forum for the relevant discussions to take place, many other organizations have been involved in the development and the maintenance of the SI system.

Keats has proposed is an approach as rigorously mathematical as the metric system, that will prioritize the individual rather than the planet.
