Jerry,

The official language of SI and the BIPM is French.
American English is defined (for spelling) by the US Government Printing 
Office.  NIST, under the US Department of Commerce, conforms with the GPO with 
respect to spellings meter and liter.

The BIPM lists l, and L in that order as symbols for litre.  NIST recommends L 
for liter.

The tonne is French.  The "metric ton" is a US term, not an invention of the 
BIPM.

Please download and study copies of official documents of the BIPM and NIST on 
SI so that you don't jump to so many false conclusions that you post to this 
list.

Gene.
