Hi everyone,

I'm sure that this will be a relatively simple questions for you experts, but I'm thoroughly confused trying to code this program. I have been assigned in school to create a temperature converter that converts celsius to farenheit and vice versa. I tried searching for code on the net, but none of the examples that I found use the same formula that I'm required to use. I must use the following formulae:
F = (40 + C)*9/5 - 40 and
C = (40 + F)*5/9 - 40

This is the code that I'm trying to insert this formula into:
___________________________________________________________
<INPUT TYPE = "text"
NAME = "cels"
VALUE = "0"
SIZE = "3"
MAXLENGTH = "3"
onChange = "fahr.value =
Math.round(40 + this.value * 9.0/5.0 - 40);"> &#176; <STRONG>C</STRONG>
&nbsp; <STRONG>equals</STRONG> &nbsp;
<INPUT TYPE = "text"
NAME = "fahr"
VALUE = "32"
SIZE = "3"
MAXLENGTH = "3"
onChange = "cels.value =
Math.round(40 + this.value * 5.0/9.0 - 40);">
&#176; <STRONG>F</STRONG>*
_____________________________________________________________

The outputs are not correct, and I just can't figure out how to arrange this formula so that it works. Any help that you could give me would be greatly appreciated!

Thanks,
Matt
