I am also trying to do a converter using a string input. e.g.: How many meters in 5 miles?
It will pull the "meters" the "5" and the "miles" from the string, do the math, and return the output.

code:
<html>
<head>
<title>String Converter</title>

<script language="Javascript" type="javascript/text">

function Convert (string1) {

if (/\smeters\s.+\d+.*\smiles/i.test(string1)){
var num1=Number(/\d+/.exec(string1));
var num2=num1/0.0006214;
document.form1.output.value=num1 +'miles is equal to' + num2 'meters.';
}


if (/\sinches\s.+\d+.*\smeters/i.test(string1)){
var num1=Number(/\d+/.exec(string1));
var num2=num1/0.00254;
document.form1.output.value=num1 +'meters is equal to' + num2 'inches.';
}

if (/\scentimeters\s.+\d+.*\sinches/i.test(string1)){
var num1=Number(/\d+/.exec(string1));
var num2=num1/0.3937;
document.form1.output.value=num1 +'inches is equal to' + num2 'centimeters.';
}

if (/\scentimeters\s.+\d+.*\smiles/i.test(string1)){
var num1=Number(/\d+/.exec(string1));
var num2=num1/0.00000621371192;
document.form1.output.value=num1 +'miles is equal to' + num2 'centimetres.';
}

if (/\slitres\s.+\d+.*\squarts/i.test(string1)){
var num1=Number(/\d+/.exec(string1));
var num2=num1/1.05669;
document.form1.output.value=num1 +'US quarts is equal to' + num2 'litres.';
}

if (/\sgrams\s.+\d+.*\spounds/i.test(string1)){
var num1=Number(/\d+/.exec(string1));
var num2=num1/0.002205;
document.form1.output.value=num1 +'miles is equal to' + num2 'meters.';
}
else{
alert('Please enter a valid conversion');
document.form1.input.focus();
}
}


</script>

</head>
