Program to Convert centimeter to millimeter

Program 1: Write a Program in C for converting the value of cm into millimeter.

#include<stdio.h>  
int main()   
{  
double value_in_cm = 40.8;  
double millimeter;  
millimeter = value_in_cm * 10;  
printf ("Value in millimeter is: %.2f \n", millimeter);   
return 0;  
}  

Output:

Value in millimeter is: 408.00

Program 2: Write a Program in PHP for converting the value of cm into millimeter.

<?php   
// This is a PHP program which converts the value of cm into the value of millimeter   
$cm = 105;   
$millimeter = $cm * 10;   
echo("Value of 100 cm in millimeter is " . $millimeter . "\n");   
?>  

Output:

Value of 105 cm in millimeter is 1050

Program 3: Write a Program in Java for converting the value of cm into millimeter.

// This is a Java program which converts the value of cm into millimeter  
import java.io.*;   
class convert {   
static double Conversion_cm_to_millimeter(double cm)   
{   
double millimeter;  
millimeter = cm * 10;    
System.out.printf("Value in millimeter is: %.2f \n", millimeter);   
return 0;   
}    
public static void main(String args [])   
{   
double cm = 1.5;  
Conversion_cm_to_millimeter(cm);   
}  
}  

Output:

Value in millimeter is: 15.00

Program 4: Write a Program in Python for converting the value of cm into millimeter.

# This is a Python program which converts the value of cm into millimeter  
  
cm = int(input("Enter the length in cm:")) // Takes the input from user.   
#convert cm to millimeter  
millimeter = cm * 10;    
  
print("The length in millimeter",round(millimeter,2))  

Output:

Enter the length in cm: 250
The length in millimeter 2500
