In this example, I’m going to show you how you can convert seconds to hours and minutes without using any library. Most of the time, duration is stored to the database in the form of seconds. This is because time conversions at various layers can get confusing and time taking. Let’s have a look at the code you can use to beautifully show the converted time:

<template>
  <div id="app">
    <label for="timeInSeconds" class="np-label">Enter time in seconds</label>
    <input
      type="number"
      v-model="timeDurationInSeconds"
      id="timeInSeconds"
      class="np-input"
    />
    <div class="np-duration" v-if="timeDurationInSeconds">
      That's roughly {{ getTimeInHoursAndMins(timeDurationInSeconds) }}
    </div>
    <div class="np-ft">
      <small> www.nightprogrammer.com </small>
    </div>
  </div>
</template>

<script>
export default {
  name: "App",
  data() {
    return {
      timeDurationInSeconds: 0,
      hoursText: "hrs",
      minsText: "mins",
    };
  },
  methods: {
    getTimeInHoursAndMins(timeInsSeconds) {
      if (timeInsSeconds && timeInsSeconds > 0) {
        const minsTemp = timeInsSeconds / 60;
        let hours = Math.floor(minsTemp / 60);
        const mins = minsTemp % 60;

        if (hours !== 0 && mins !== 0) {
          if (mins >= 59) {
            hours += 1;
            return +`${hours} ${this.hoursText} `;
          } else {
            return `${hours} ${this.hoursText} ${mins.toFixed(0)} ${
              this.minsText
            }`;
          }
        } else if (hours === 0 && mins !== 0) {
          return `${mins.toFixed(0)} ${this.minsText}`;
        } else if (hours !== 0 && mins === 0) {
          return `${hours} ${this.hoursText}`;
        }
      } else {
        return "-";
      }
    },
  },
};
</script>

In the above code, I’ve used a local state timeDurationInSeconds to store the value of user input time in seconds. I’ve then used a method called getTimeInHoursAndMins to convert the time in hours and minutes. I’ve put various checks for the combinational validity of hours and minutes through line numbers 36 and 50.

Here’s a working version of the above code from my repos:
