I know this is a little old, but this is incorrect.

You may refer to section 5.2 of the SI brochure (http://www.bipm.org/utils/common/pdf...chure_8_en.pdf), which specifies that__names__of all units are treated as ordinary nouns and start with a lower-case letter even when the symbol for the unit begins with a capital letter. Section 5.1 states that the first letter of a__symbol__is capitalized only if it is derived from a proper name (for instance Hz for hertz), or to avoid confusion (for instance, litre is allowed to be represented by L since the lower-case el looks the numeral one).
