Go to http://www.copernic.com They have a super search engine in two varieties. One is free, the other is shareware. I have downloaded the free Copernic 2001 Basic. It uses a large number of well kinowen search engines. I found 64 entries on 'metric' for instance, and most of them were on the metric system. There are probnably many other possiblilities to find metric information. I searched the Web, (quick search) but there are many other ways to search, When you have a list of entries, you can link on there, either to its own browser or to yours. That can be selected. Just download it and play with it,
