I found this code here: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1260490119

double Thermister(int RawADC) {
double Temp;
Temp = log(((10240000/RawADC) - 10000));
Temp = 1 / (0.001129148 + (0.000234125 * Temp) + (0.0000000876741 * Temp * Temp * Temp));
Temp = Temp - 273.15;            // Convert Kelvin to Celcius
return Temp;
}

and using it with my temperature brick (http://www.seeedstudio.com/depot/electronic-brick-temperature-sensoranalog-p-478.html) but is it actually the right formular I am using for it?
