1 Litre will also fit quite nicely in a cube 10cm a side. For a person whom has used the metric for 2/3 of my life I still find it very clear and precise. I hate to have to remember all those weird numbers 5280 feet in a mile, 16 ounces to a can oh wait that's beer here... It took me a while to get used to the units on this side of the pond and I still strugglt when I need a pint and all I have to measure is a cup. And I found the most people here don't even know all those psychoweirdo stuff. Hey the Nasdaq just dropped the fractional notation. That's another funky stuff I had to deal with adding 3/32 of an inch to 3/8 of an inch does not look like fun to me when I could be adding mm or cm. Look what happened when one bonehead uses Imperial measurements instead of the standard metric system for the mars smasher ^H^H^H^H^H^H lander. I don't think the US will ever make it to the metric system. It is always presented as a difficult system in schools. some kids always ooh aah when I mention the metric stuff to them. Wake up people of the United states it's 2001 and we don't need to know the lenght of the thumb or foot or whatever appendage from some long dead ruler of an old island. Francois
