The values of the constants provided at this site are recommended for international use by CODATA and are the latest available. Termed the "1998 CODATA recommended values," they are generally recognized worldwide for use in all fields of science and technology. The values became available in July 1999 and replaced the 1986 CODATA set. They are based on all of the data available through 31 December 1998. A detailed description of the data and the analysis that led to these values may be found in the Journal of Physical and Chemical Reference Data, Vol. 28, No. 6, pp. 1713-1852, 1999 and in the Reviews of Modern Physics, Vol. 72, No. 2, pp. 351-495, 2000. That paper (abstract below) was prepared under the auspices of the CODATA Task Group on Fundamental Constants. Also available is an Introduction to the constants for nonexperts.

Ok. How about other CGS units? e.g. ergs, etc (any others?). What
about adding the Joule and Newton to be symmetrical in going from MKS
to CGS?
Also if anybody knows of any good sets of data, like atomic weights of
the elements, or astronomical data like planetary masses, it would be
useful to have those sorts of things too.
