Most features (if not all) will work with versions of Internet Explorer 4.0 or later. Some facilities are not available in Netscape 4 but are available in later versions of Netscape. Earlier versions of Netscape and IE than these and other brands of browser have not been tested and are not supported.

Note that some of the converter tables are quite large and so may take some time to load. This applies in particular to the Mass, Length and Volume converters. Please allow time for the tables to load. The alternative would be to remove some of the units, thus reducing the coverage. If this is still a problem, please let us know. Note that some tables have been split into several smaller tables to provide modern, historical and world measures.

  - Select either "Automatically" (preferred) or "Every time you start Internet Explorer". Do NOT select "Every visit to the page" as this will cause your browser to re-read every file for each page every time you access a page, even files that are shared between pages and are held in the browser's cache. This significantly increases the time required to load each page.
