Subject: Symbols for SI Prefixes
Dear Barry,
Considerable support is being expressed again by me and my
associates for CCU approval of *both* alternative symbols in three
instances:
da or D for deca,
h or H for hecto, and
k or K for kilo, for at least a trial period,
Subsequent approvals by the CIPM and the CGPM would enable
the option of *all* upper case symbols for multiples greater than one.
This improvement would greatly enhance the appeal of SI to students.
The president for alternative symbols is l or L for liter,
Both of these symbols are currently approved for a trial period.
Furthermore, Council Directive 80/181/EEC of the European Union
*replaces* k by K for kilo, and *replaces* h by H for hecto.
The question of D replacing da, or approval of both da and D as
alternatives is not addressed by CD 80/181/EEC.
Please seek approval of da or D, h or H, and k or K, at least
for a trial period, at the CCU meeting in 2001 April 19 and 20.
Who objected to this proposal at the CCU meeting in 1998 and why?
Sincerely,
Eugene A. (Gene) Mechtly, College of Engineering
University of Illinois at Urbana-Champaign (uiuc)
