moe wrote:the correct character symbol for litres in the International System of Units (SI), the current metric system if you like, is an uppercase L
this was set in SI over thirty years ago because of the confusion of:
l l
being one litres or eleven. this was especially true in the health profession
note that SI is case sensitive ... meaning that all the prefixes and units have specific character symbols

Actually Moe, Your incorrect on serveral points here.
Section 6.1.2 "Capitalization" of The International System of Units (SI), Ed. by B. N. Taylor, Natl. Inst. Stand. Technol. Spec. Publ. 330, 1991 Edition States:
Unit symbols are printed in lower-case letters except that:
(a)
the symbol or the first letter of the symbol is an upper-case letter when the name of the unit is derived from the name of a person; and
(b)
the recommended symbol for the liter in the United States is L [see Table 6, footnote (b).
table six Footnote (b) States:
(b) The alternative symbol for the liter, L, was adopted by the CGPM in order to avoid the risk of confusion between the letter l and the number 1 (see Ref. [2] or [3]). Thus, although both l and L are internationally accepted symbols for the liter, to avoid this risk the symbol to be used in the United States is L (see Refs. [1] and [8]). The script letter §¤ , is not an approved symbol for the liter.
So, both "l" and "L" are internationally accepted symbols for the liter.
Moe, you seem to be perusing the web site looking for errors to point out, rather than for questions to answer. Might I suggest that answering questions is a far better way to demonstrate you knowledge? The use of "L" or "l", "s" or "sec" is not this point of this web site. The site is here to help people understand how to convert things. not to create a flame war about upper or lower case.
