Thanks for your interest, and your > help. I've sent my code to Trans. If your interested, please contact him. I've not addressed the temperature problem as I'm still not very happy with it. My current opinion is that maybe temperature conversion should be done by separate methods, and only Kelvin should be allowed in the whole units machinery. As Kelvin has the absolute zero temperature as reference point, there are no problems in its use. Besides, we were taught in science class to first convert all temperatures to Kelvin, then do all calculations, and then convert temperatures back if necessary, so this restriction should pose few problems (for me at least).
