Java Printf Alignment Output

All I would like to know what's wrong with this is why do things get pushed to the right when there is 3 numbers a decimal point and a decimal. Why isn't this being aligned? I've had this problem with other code, even copied someones code that should've displayed decimal points aligning in a column but it always doesn't align. Please ignore everything above "_________________________________" line, I know it's not aligned with that, i just want to know why it's doing what it's doing below that line. (why mis aligning everything by pushing top 3 rows to the right)

What the actual answer is supposed to look like according to book answer result

Books Answer Code

package Ch5_Methods;
import java.util.Scanner;
public class testch5 {

public static void main(String[] args) {
    // TODO Auto-generated method stub

    System.out.printf("%-15s%-15s|    %-15s%-15s\n","Celsius","Fahrenheit","Fahrenheit","Celsius");
      System.out.println( String.format("%62s"," ").replace(' ', '-') );

      for (int c = 40, f = 120  ; c >=31; c--, f-=10) {

       System.out.printf("%-15.1f%-15.1f|    %-15.1f%-15.2f\n",(float)c,celsiusToFahrenheit(c),(float)f, fahrenheitToCelsius(f));

      }


     }

     /** Convert from Celsius to Fahrenheit */
     public static double celsiusToFahrenheit(double celsius) {
      return (9.0 / 5) * celsius + 32;
     }

     /** Convert from Fahrenheit to Celsius */
     public static double fahrenheitToCelsius(double fahrenheit) {
      return (5.0 / 9) * (fahrenheit - 32);

    }




}

I cannot figure out how to align the code, I've tried formatting different ways with printf, I'm still a beginner and i'm sure there is an easier way to do this, but i'm trying to accomplish this having only covered methods, loops, if/else, formatting and other basic stuff.

You can see that periods take up less space than the other characters. You need to switch to a mono spaced font. Eclipse has some documentation for how to do that here.
