In this guide, we will see programs to convert Kilometres to Centimetres in various programming languages such as Java, C, C++, Python, PHP. The kilometres and centimetres both are the unit of lengths.
Formula to convert Kilometres to Centimetres
cm = km * 100000
Multiply the km by 100000 to get the length in cm.
Input: .5 km Output: 50000 cm
Java Program
// Java program to convert length given in Kilometres into centimetres
class JavaExample {
public static void main(String args [])
{
double km = 2;
double cm;
cm = 100000 * km;
System.out.println(km+ "km = "+cm+" cm");
}
}
Output:
2.0km = 200000.0 cm
C Program
#include<stdio.h>
int main()
{
double km = 3, cm;
//kilometres to centimetres conversion
cm = 100000 * km;
printf ("3 kilometres = %.2f centimetres", cm);
return 0;
}
Output:
3 kilometres = 300000.00 centimetres
C++ Program
// C++ Program to Convert kilometres to centimetres
#include <iostream>
using namespace std;
int main(){
double km, cm;
// User is asked to enter the length in kilometres
cout << "Enter the length in kilometres: ";
cin >> km;
// converting length from km to cm
cm = km * 100000;
// displaying length in centimetres
cout << "The length in centimetre is: " << cm;
return 0;
}
Output:
Enter the length in kilometres: 1.5 The length in centimetre is: 150000
Python Program
# Python program to convert length given in km to cm
km = float(input("Enter the length in kilometres: "))
# convert km to cm by multiplying the value in km by 100000
cm = 100000 * km;
print("The length in centimetre is: ",round(cm,3))
Output:
Enter the length in kilometres: .25 The length in centimetre is: 25000.0
PHP Program
<?php
// PHP program for kilometres to centimetres conversion
$km = 5.5; //length in kilometres
$cm = 100000 * $km; //conversion from km to cm
echo("The length in centimetres is: " . $cm);
?>
Output:
The length in centimetres is: 550000
