# Converting km per hour to cm per second using JavaScript

## Problem

We are required to write a JavaScript function that takes in a number that specifies speed in kmph and it should return the equivalent speed in cm/s.

## Example

Following is the code −

const kmph = 12; const convertSpeed = (kmph) => { const secsInHour = 3600; const centimetersInKilometers = 100000; const speed = Math.floor((kmph * centimetersInKilometers) / secsInHour); return `Equivalent in cmps is: ${speed}`; }; console.log(convertSpeed(kmph));

## Output

Equivalent in cmps is: 333
