How To Switch Sides

I had to make a chart where it took miles 1-10 and convert it to kilometers and then on the other side it needs to show 25-65 (in 5's) kilometers to miles and I dont know how to switch the sides...

import java.util.Scanner;
public class MilesAndKilos {
public static void main(String[] args) {
int miles;
double kilometers=1.60934;
System.out.println(" Miles Kilometers Kilometers Miles");
for(miles=1;miles<10;miles++){
kilometers = miles * 1.60934;
System.out.printf(" %2d %8.3f |
", miles,kilometers);
}
}//end of main method
}
