How to convert seconds to minutes and hours in JavaScript

Today we will show you how to convert seconds to minutes and hours in JavaScript. In other words, convert into hh mm ss from seconds.

Example

Let’s take an example, where you want to convert for example 1248 seconds to 20m 48s.

If the converted time is more than 1 hours for example 9489 seconds then it should be 2h 38m 09s.

Function

Following function will return the converted value from the seconds to hh mm ss.

function secondsToHms(seconds) {
  if (!seconds) return '';

  let duration = seconds;
  let hours = duration / 3600;
  duration = duration % (3600);

  let min = parseInt(duration / 60);
  duration = duration % (60);

  let sec = parseInt(duration);

  if (sec < 10) {
    sec = `0${sec}`;
  }
  if (min < 10) {
    min = `0${min}`;
  }

  if (parseInt(hours, 10) > 0) {
    return `${parseInt(hours, 10)}h ${min}m ${sec}s`
  }
  else if (min == 0) {
    return `${sec}s`
  }
  else {
    return `${min}m ${sec}s`
  }
}

Output

secondsToHms(1248); // Output: 20m 48s
secondsToHms(9489); // Output: 2h 38m 09s

That’s it for today.
