Exactly, Gustaf. The stress on the use of 1000-multiples and
sub-multiples was so strong that even I was convinced that 'the cm
isn't SI' until very recently. But the BIPM reference quite clearly
gives the centi- etc. prefixes as perfectly valid (and they're not
listed alongside other things which are merely being 'tolerated').
