Nanometer to milimeter: In the previous article we have discussed about Java Program to Convert Millimeter to Micrometer and Micrometer to Millimeter

In this article we will see how to convert Millimeter to Nanometer and Nanometer to Millimeter by using Java programming language.

Java Program to Convert Millimeter to Nanometer and Nanometer to Millimeter

Nanometer in millimeter: Before jumping into the program let’s know the relationship between Millimeter and Nanometer.

Generally Millimeter is used to measure very small length mainly we use to measure visible scale distances and Nanometer is used to measure very very small things like atoms and molecules.

1 Millimeter = 1000000 Nanometer
1 Nanometer =  1e-6 Millimeter

Formula to convert Millimeter to Nanometer.

Nanometer = Millimeter * 1e+6

Formula to convert Nanometer to Millimeter.

Millimeter = Nanometer / 1e+6

Let’s see different ways to convert Millimeter to Nanometer and Nanometer to Millimeter.

Method-1: Java Program to Convert Millimeter to Nanometer and Nanometer to Millimeter By Using Static Input Value

Approach:

  • Declare Millimeter and Nanometer value.
  • Then convert Millimeter to Nanometer and Nanometer to Millimeter 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 nanometer declared
        double nanometer = 1;
        //value of millimeter declared 
        double millimeter = 1;

        //converting millimeter to nanometer
        double nm = millimeter * 1e+6;
        //converting nanometer to millimeter
        double mm = nanometer / 1e+6;
        //printing result
        System.out.println("Value of "+nanometer+" nanometer in millimeter: "+ mm);   
        System.out.println("Value of "+millimeter+" millimeter in nanometer: "+ nm);   
   }
}
Output:

Value of 1.0 nanometer in millimeter: 1.0E-6
Value of 1.0 millimeter in nanometer: 1000000.0

Method-2: Java Program to Convert Millimeter to Nanometer and Nanometer to Millimeter By Using User Input Value

Approach:

  • Take user input of Millimeter and Nanometer value.
  • Then convert Millimeter to Nanometer and Nanometer to Millimeter 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 nanometer
        System.out.println("Enter value of nanometerr: ");  
        double nanometer = sc.nextDouble();
        //Taking the value input of double variable millimeter
        System.out.println("Enter value of millimeter: ");  
        double millimeter = sc.nextDouble();

        //converting millimeter to nanometer
        double nm = millimeter * 1e+6;
        //converting nanometer to millimeter
        double mm = nanometer / 1e+6;
        //printing result
        System.out.println("Value of "+nanometer+" nanometer in millimeter: "+ mm);   
        System.out.println("Value of "+millimeter+" millimeter in nanometer: "+ nm);   
   }
}
Output:

Enter value of nanometerr: 
5000000
Enter value of millimeter: 
5
Value of 5000000.0 nanometer in millimeter: 5.0
Value of 5.0 millimeter in nanometer: 5000000.0

Method-3: Java Program to Convert Millimeter to Nanometer and Nanometer to Millimeter By Using User Defined Method

Approach:

  • Take user input of Millimeter and Nanometer value.
  • Call a user defined method by passing Millimeter and Nanometer value as parameter.
  • Inside method convert Millimeter to Nanometer and Nanometer to Millimeter 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 nanometer
        System.out.println("Enter value of nanometerr: ");  
        double nanometer = sc.nextDouble();
        //Taking the value input of double variable millimeter
        System.out.println("Enter value of millimeter: ");  
        double millimeter = sc.nextDouble();
        //calling user defined method convert()
        convert(nanometer, millimeter);
   }
   
   //convert() method to convert nanometer to millimeter and vice versa
   public static void convert(double nanometer, double millimeter)
   {
        //converting millimeter to nanometer
        double nm = millimeter * 1e+6;
        //converting nanometer to millimeter
        double mm = nanometer / 1e+6;
        //printing result
        System.out.println("Value of "+nanometer+" nanometer in millimeter: "+ mm);   
        System.out.println("Value of "+millimeter+" millimeter in nanometer: "+ nm);   
   }
}
Output:

Enter value of nanometerr: 
60000
Enter value of millimeter: 
6
Value of 60000.0 nanometer in millimeter: 0.06
Value of 6.0 millimeter in nanometer: 6000000.0
