Actually neither system is any more scientific than the other. Metric seems more methodical but only because we use the base 10 system of Mathematics. Most involvement with computers is tied to the base 2 system. Maybe in a 100 years the base 10 system will have gone the way of the Dodo bird.

Pierre's rationale for changing to metric is because our trading partners around the world were on the metric system. IT's not an excuse for changing the whole system. We can still put 10 kg. of sugar in a bag w/o having to change to the metric system.
