Write a program in C to convert distance from kilometer to meter, centimeter and millimeter.
WAP in C to convert kilometer(km) to meter(m).

Required Knowledge

• C printf and scanf functions
• C Arithmetic Operators

We will first take distance in kilometer(km) as input from user using scanf function and then convert it to meter, centimeter and millimeter using following formulae.

• 1 Kilometer = 1000 Meter
• 1 Kilometer = 100000 Centimeter
• 1 Kilometer = 1000000 Millimeter

C program to convert kilometer to meter, centimeter and millimeter

/** 
 * C program to convert kilometer into meter, 
 * centimeter and millimeter 
 */  
  
#include <stdio.h>  

int main() {  
   float meter, centimeter, millimeter, kilometer;  
  
   /* 
    * Take length in Kilimeter as input form user
    */  
   printf("Enter Length in Kilometer(km)\n");  
   scanf("%f", &kilometer);  
  
   /* 
    * 1 km = 1000 m, 1 km = 100000 cm, 1 km = 1000000 mm 
    */  
   meter = kilometer * 1000;  
   centimeter = kilometer * 100000;
   millimeter = kilometer * 1000000;
  
   printf("%.4f Kilometer = %.4f Meter\n", kilometer, meter);  
   printf("%.4f Kilometer = %.4f Centimeter\n",kilometer,centimeter);  
   printf("%.4f Kilometer = %.4f Millimeter\n",kilometer,millimeter);  
  
   return 0;  
} 

Output

Enter Length in Kilometer(km)
4.0
4.0000 Kilometer = 4000.0000 Meter
4.0000 Kilometer = 400000.0000 Centimeter
4.0000 Kilometer = 4000000.0000 Millimeter
