JavaScript Program to Convert Kilometers to Miles

In this example, you will learn how to convert the kilometers value to miles in JavaScript.

We know that 1 kilometer is equal to 0.621371 miles.

So to convert kilometers to miles, you can use the formula:

miles = kilometers * factor

Example 1: Kilometers to Miles

// taking kilometers input from the user
let kilometers = prompt("Enter value in kilometers: ")

// conversion factor
let factor = 0.621371

// calculate miles
let miles = kilometers * factor

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


Enter value in kilometers: 2.2
2.2 kilometers is equal to 1.3670162000000001 miles.

Here, the kilometers variable is used to store the kilometer value from the user. Then kilometer value is multiplied with the factor to convert into miles.

To convert miles to kilometers, you can use formula:

kilometers = miles / factor
