# Convert Kilometers To Miles In C++

What we are going to see through this article is we will see in detail Convert Kilometers To Miles In C++. We make a Simple Program About Miles to Kilometers (mi to km) conversion calculator for Length conversions with additional tables and formulas.

Input: 10 kilometers

Output:  6.21 miles

The program will use a unit formula to convert distance unit kilometers to miles.

For example, 10 kilometers = —– miles?

Since, 1 km =   0.621 miles

hence, 10 km = 10*0.621 = 6.21 miles.

## Convert Kilometers to Miles in C++

``````#include <iostream>
using namespace std;

float KilometersToMilesConversion(float kilometers) {

// 1 kilometer = 0.621

float miles = kilometers * 0.621;

return miles;

}

//Test program
int main()
{
float kilometers;
cout << "Enter the distance in kilometers:";

cin >> kilometers;

//Call conversion function

float miles = KilometersToMilesConversion(kilometers);

cout << kilometers << " is equal to "<< miles << " Miles";

return 0;
}``````
