Paul Giaccone Sent:
Centi-, deci-, deca- and hecto- are not officially part of SI nomenclature.
That's not what the Bureau Internatoinal des Poids et Mesures (http://www.bipm.org/en/si/si_brochure/chapter3/prefixes.html) says.
Does the second officially take any prefix? Can you talk about a "megasecond", Yes. (Although it is EXTREMELY unusual).
or would you convert this to the more usual "11 days, 13 hours, 46 minutes and 40 seconds"? Indeed, does the library have a mechanism for doing this sort of breakdown of time? I suspect not, as time is not base 10.
Is the litre officially an SI unit? According to http://www.bipm.org/en/CGPM/db/16/6/ it wasn't in 1980. I think it unlikely to have become one since.
It looks like there is a large number of things to consider in this library. I hope the ever-growing wish list doesn't end up pushing the release date of the library back for ever or causing it to end up being rejected just because there is a host of extra requirements that it does not yet fulfil.
