Write a Java program to input centimeter and convert to inch, meter and kilometer. How to convert centimeter to inch, meter and kilometer in Java programming.

**Example**

**Input**

Enter centimeter : 12.5

**Output**

12.5 cm is equal to 4.925 inch. 12.5 cm is equal to 0.125 meter. 12.5 cm is equal to 4.925 kilometer.

## Required knowledge

Basic Input/Output, Arithmetic operators

## Logic to convert centimeter to inch, meter and kilometer

Step-by-step explanation of how can we convert centimeter to inch, meter and kilometer.

- Let us first establish relation between centimeter, inch, meter and kilometer.
`1 cm = 0.394 inch 1 cm = 0.01 meter 1 cm = 0.00001 kilometer`

- After you know how many inches, meters and kilometers are there in 1 centimeter. You can easily find total inches, meters and kilometers in centimeter. To get desired result, multiply given centimeter to inches/meters/kilometers in 1 centimeter.

**Example:**`10 cm = 10 * 0.394 inches = 3.94 inches 10 cm = 10 * 0.01 m = 0.1 m 10 cm = 10 * 0.00001 = 0.0001 km`

## Program to convert centimeter to inch, meter and kilometer

```
/**
* Java program to convert centimeter to inch, meter and kilometer.
*/
import java.util.Scanner;
public class MeasurementConversion {
public static void main(String[] args) {
/*
* Constants for inch, meter and kilometer in 1 centimeter.
*/
final double INCH = 0.394;
final double METER = 0.01;
final double KILOMETER = 0.00001;
Scanner in = new Scanner(System.in);
/* Read centimeter input from user */
System.out.print("Enter length in centimeters : ");
double cm = in.nextDouble();
/* Convert cm into inch, m and km */
double inch = cm * INCH;
double m = cm * METER;
double km = cm * KILOMETER;
/* Print result on console */
System.out.println(cm + " cm is equal to " + inch + " inches.");
System.out.println(cm + " cm is equal to " + m + " meters.");
System.out.println(cm + " cm is equal to " + km + " kilometers.");
}
}
```

Output

Enter length in centimeters : 12.5 12.5 cm is equal to 4.925 inches. 12.5 cm is equal to 0.125 meters. 12.5 cm is equal to 4.925 kilometers.
