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.
Interesting... I stand corrected. But are they in official scientific use?
Does the second officially take any prefix? Can you talk about a "megasecond",
Yes. (Although it is EXTREMELY unusual).
Quoting your source back at you, Martin... according to the section at the bottom of the page, you can't officially say "megasecond". Paul
