This is a javascript question, despite the code being in php, thus in the wrong forum.

try[codeg<script language="JavaScript" >
function to_m(){
	var f = document.getElementById('f').value;
	var m = f*0.0283168466;
	document.getElementById('m').value = m;
}
function to_f() {
	var m = document.getElementById('m').value;
	var f = m/0.0283168466;
	document.getElementById('f').value = f;
}
</script>

<form method='post' action=''>
<input type='text' name='CubicFeet' id='f' onkeyup='to_m()'> CubicFeet <br />
<input type='text' name='CubicMeters' id='m' onkeyup='to_f()'> CubicMeters
</form>
