I don't remember the proper units for this. (Probably something like Pa*s/l). By the way, coulombs (C), is the measure of electrical quantity not amperes, wattage is the measure of energy or the ability of a system to do work, and ohms gives an indication of energy loss. ------------------------------------------------------------------------------- Andy Nagy (ptoper@asterix.gaul.csd.uwo.ca) The University of Western Ontario, London, Canada "Dee do do do, dee da da da, thats all I want to say to you" -- The Police
