JavaScript Program to Convert Kilometers to Miles

JavaScript is a powerful and versatile programming language that can be used to create a wide range of applications and websites. In this tutorial, we will learn how to write a JavaScript program to convert kilometers to miles. We will use a simple formula to perform the conversion, and the program will prompt the user to input a value in kilometers and then display the equivalent distance in miles.

This program can be useful for anyone who needs to quickly and easily convert distances from one unit of measurement to another. We also have an interactive JavaScript course where you can learn JavaScript from basics to advanced and get certified. Check out the course and learn more from here.

The main approach here is to find the Conversion Factor to convert Kilometers to Miles, which we will need to multiply with the Kilometers to get the desired miles in return.

Basic Formula:

1 kilometer is equal to 0.621371 miles.

Note: To convert back kilometers from miles we need to divide the miles by a factor of 0.6211371

Code:

// Program to convert Kilometers to Miles
const km = prompt("Enter value in kilometers: ")

// conversion factor
const factor = 0.621371

const miles = km * factor

console.log(`${km} kilometers is equal to ${miles} miles.`);

Enter value in kilometers: 5.5
5.5 kilometers is equal to 3.4175405 miles.

Conclusion

In conclusion, a JavaScript program can be easily written to convert kilometers to miles. The use of a simple formula and user input allows the program to perform the conversion quickly and accurately. By providing a user-friendly interface and the ability to perform the conversion on demand, this program can be a useful tool for anyone who needs to work with distances measured in different units of measurement. Overall, the use of JavaScript in this program demonstrates the language's versatility and ability to create practical and useful applications.
