function calculate()

{

var c = document.form1.celcius.value;

var f = document.form1.farenheit.value;

var resultF;

var resultC;

var result="";

if(c!="")

{

resultF = c * 9 / 5 + 32;

result = c+'\xB0C is ' + resultF + ' \xB0F.';

}

if(f!="")

{

resultC = (f - 32) * 5 / 9;

result += '\n' + f +'\xB0F is ' + resultC + '\xB0C.';
