Woody, there's an online calculator at this link:  http://www.brucelindbloom.com/

once you get there, click "calc" in the menu bar.  on the next page, click "companding 
calculator" which is the second from the top.  in the calculator, enter your L values in the L 
value field, click on the L button, and it will calculate density.  i found this calculator 
thanks to a mention by carl schofield, i think.
