If you insert the script that follows into a new web page, save it, and then open it in your browser one can readily convert C and F. If you don't have an html editor, it can be done with most browsers, if there is interest I can post those instructions. <HTML> <HEAD> <BODY BGCOLOR="#FFFFFF"> <TITLE>Temperature Coversion</TITLE> <H1> </H1> <CENTER> <TABLE BORDER=0 CELLSPACING=0 CELLPADDING=5 WIDTH="100%" > <TR> <TD VALIGN=TOP> <H3>Temperature Conversion</H2> Enter a number in either field, then <ul><li>click outside the text box, or <li>press the tab key. </ul> <form> F: <input type="text" name="F" value="32" onChange="eval('C.value = ' + this.form.C_expr.value)" size="20"> <input type="hidden" name="F_expr" value="(212-32)/100 * C.value + 32 "> C: <input type="text" name="C" value="0" onChange="eval('F.value = ' + this.form.F_expr.value)" size="20"> <input type="hidden" name="C_expr" value="100/(212-32) * (F.value - 32 )"> <input type=reset name=reset value=reset> </form> <P> This script converts from celcius to farhenheit and vice versa. <P></TABLE> </HTML> Mark Mazer Intarsia Ltd.
