Temperature Conversion using Array not working?

so I'm trying to convert numbers in an array from fahreneheit to celcius; I'm not getting any errors, but my numbers are definitely not right. here is my code:

package lab7q2;

public class Lab7Q2 {

/**
 * @param args the command line arguments
 */
public static void main(String[] args) {
    // TODO code application logic here


    int[] tempList = {212, 95, 64, 32, 0, -12, -25};

    for (int i = 0; i < tempList.length; i++) {
        System.out.format("temp in F %4d  temp in C %6.2f \n", + tempList[i], tempFtoC(i));
    }


}

public static double tempFtoC (int tempList) {

    double tempC = ((tempList - 32)*5)/9;
    return tempC;
    }

}

and here is my output:

temp in F  212  temp in C -17.00 
temp in F   95  temp in C -17.00 
temp in F   64  temp in C -16.00 
temp in F   32  temp in C -16.00 
temp in F    0  temp in C -15.00 
temp in F  -12  temp in C -15.00 
temp in F  -25  temp in C -14.00 
BUILD SUCCESSFUL (total time: 0 seconds)

can anyone tell my why its not doing the conversion right? Is my method not set up correctly? (new to programming, so please don't be too rough with me...)

You are converting i, not tempList[i], so you should change your format statement to

System.out.format("temp in F %4d  temp in C %6.2f \n", + tempList[i], tempFtoC(tempList[i]));
