Dear Gene,
i was unaware of your prior efforts to suggest a scheme of upper casing of symbols for multiples greater than one to the SI Consultive Committee on Units (CCU). speaking for myself, i don't have a problem with an upper casing of the prefix symbol 'K' for kilo. at the same time, i can respect the tradition of a lower casing of the prefix symbol 'k' for kilo (which is specified in recent versions of the SI). although i do not wish to speculate why the CCU did not update the expression of prefix symbols for multiples greater than one in terms of a scheme of an upper case symbol; i also haven't seen a rationale for the upper casing of symbols for multiples greater than one, or for the lower casing of symbols for submultiples (or multiples less than one). moreover, i haven't seen a rationale for maintaining exceptions to these schemes in standards documents. although updates for these identified improvements might not be on a fast track, i would not give up hope for their practicable use with SI. for my part I will copy this information to AAT ICAS to be sure that a specification of the casing of symbols for 'deca' and 'hecto' are not ignored in subsequent revisions of the AAT ICAS 0600s08 (http://www.aatideas.org/iota/dv/0600.xht#go0600s08) considerations on the review of case structure of metric prefixes. Cheers, Ron ps - was it y2k or y2K or Y2k or Y2K?
