Java Program to Convert Kilometer to Nautical Mile and Nautical Mile meter to Kilometer

Before jumping into the program let’s know the relationship between Kilometer and Nautical Mile and how we can convert Kilometer to Nautical Mile and vice versa.

Generally Kilometer and Nautical Mile are used as unit in case of distance measurement.

1 Kilometer = 0.539957 Nautical Mile
1 Nautical Mile = 1.852 Kilometer

Formula to convert Kilometer to Nautical Mile.

Nautical Mile = Kilometer / 1.852  (OR)  Kilometer * 0.539957

Formula to convert Mile to Kilometer.

Kilometer = Nautical Mile * 1.852

Let’s see different ways to convert Kilometer to Nautical Mile and Nautical Mile to Kilometer.

Method-1: Java Program to Convert Kilometer to Nautical Mile and Nautical Mile meter to Kilometer By Using Static Input Value

Approach:

  • Declare Kilometer and Nautical Mile value.
  • Then convert Kilometer to Nautical Mile and Nautical Mile to Kilometer by using the formula.
  • Print result.

Program:

import java.util.*;
public class Main 
{
   public static void main(String args[])
   {
        //Scanner class object created
        Scanner sc=new Scanner(System.in);
        //value of nautical mile declared
        double nauticalmile = 1;
        //value of kilometer declared 
        double kilometer = 1;

        //converting kilometer to nautical mile
        double nmi = kilometer / 1.852;
        //converting nautical mile to kilometer
        double km = nauticalmile * 1.852;
        //printing result
        System.out.println("Value of "+nauticalmile+" nautical mile in kilometer: "+ km);   
        System.out.println("Value of "+kilometer+" kilometer in nautical mile: "+ nmi);   
   }
}
Output:

Value of 1.0 nautical mile in kilometer: 1.852
Value of 1.0 kilometer in nautical mile: 0.5399

Method-2: Java Program to Convert Kilometer to Nautical Mile and Nautical Mile meter to Kilometer By Using User Input Value

Approach:

  • Take user input of Kilometer and Nautical Mile value.
  • Then convert Kilometer to Nautical Mile and Nautical Mile to Kilometer by using the formula.
  • Print result.

Program:

import java.util.*;
public class Main 
{
   public static void main(String args[])
   {
        //Scanner class object created
        Scanner sc=new Scanner(System.in);
        //Taking the value input of double variable nauticalmile
        System.out.println("Enter value of nautical mile: ");  
        double nauticalmile = sc.nextDouble();
        //Taking the value input of double variable kilometer
        System.out.println("Enter value of kilometer: ");  
        double kilometer = sc.nextDouble();

        //converting kilometer to nautical mile
        double nmi = kilometer / 1.852;
        //converting nautical mile to kilometer
        double km = nauticalmile * 1.852;
        //printing result
        System.out.println("Value of "+nauticalmile+" nautical mile in kilometer: "+ km);   
        System.out.println("Value of "+kilometer+" kilometer in nautical mile: "+ nmi);   
   }
}
Output:

Enter value of nautical mile: 
5
Enter value of kilometer: 
8
Value of 5.0 nautical mile in kilometer: 9.26
Value of 8.0 kilometer in nautical mile: 4.3196

Method-3: Java Program to Convert Kilometer to Nautical Mile and Nautical Mile meter to Kilometer By Using User Defined Method

Approach:

  • Take user input of Kilometer and Nautical Mile value.
  • Call a user defined method by passing Kilometer and Nautical Mile value as parameter.
  • Inside method convert Kilometer to Nautical Mile and Nautical Mile to Kilometer by using the formula.
  • Print result.

Program:

import java.util.*;
public class Main 
{
   public static void main(String args[])
   {
        //Scanner class object created
        Scanner sc=new Scanner(System.in);
        //Taking the value input of double variable nauticalmile
        System.out.println("Enter value of nautical mile: ");  
        double nauticalmile = sc.nextDouble();
        //Taking the value input of double variable kilometer
        System.out.println("Enter value of kilometer: ");  
        double kilometer = sc.nextDouble();
         //calling user defined method convert()
        convert(nauticalmile, kilometer);
   }
   
   //convert() method to convert nautical mile to kilometer and vice versa
   public static void convert(double nauticalmile, double kilometer)
   {

        //converting kilometer to nautical mile
        double nmi = kilometer / 1.852;
        //converting nautical mile to kilometer
        double km = nauticalmile * 1.852;
        //printing result
        System.out.println("Value of "+nauticalmile+" nautical mile in kilometer: "+ km);   
        System.out.println("Value of "+kilometer+" kilometer in nautical mile: "+ nmi);   
   }
}
Output:

Enter value of nautical mile: 
4.4
Enter value of kilometer: 
2.2
Value of 4.4 nautical mile in kilometer: 8.1488
Value of 2.2 kilometer in nautical mile: 1.1879
