Try this:

[html]<html>
<head>
<script type="text/javascript">
function convert(degree)
{
if (degree=="C")
{
F=document.myfo rm.celsius.valu e * 9 / 5 + 32
document.myform .fahrenheit.val ue=(F)
}
else
{
C=(document.myf orm.fahrenheit. value -32) * 5 / 9
document.myform .celsius.value= (C)
}
}
</script>
</head>
<body>
<form name="myform">
<input name="celsius" onkeyup="conver t('C')" size="20"> degrees Celsius<br />
equals<br />
<input name="fahrenhei t" onkeyup="conver t('F')" size="20"> degrees Fahrenheit
</form>
