A plugin for adding handy conversion filters to your Vue.js project. Based on the convert-units package made by @ben-ng.

Install vue-units with NPM from the vue-units NPM repository by running the following command:

npm install vue-units --save

If you prefer to use Yarn, you can install it with the following command instead:

yarn add vue-units

Add it to your vue instance:

import Vue from 'vue';
import VueUnits from 'vue-units';

Vue.use(VueUnits)

If you don't use ES6, you can also include it as a script locally:

<script src="https://unpkg.com/vue-units@^1.0/vue-units.js"></script>

The filter unit(from, to, includeUnit) is added to your Vue instance, which makes it easy to convert between a set of units in your templates:

<template>
  <div id="app">
    <p>{{1500 | units('m', 'km', true)}}</p>
  </div>
</template>

The above code will result in the following output:

1.5 km

If includeUnit is false, only the converted value will be returned:

1.5

To see a list of available conversion units, please refer to the official repository for convert-units.

You can access the instance of convert-units anywhere in your Vue templates, which gives you access to the additional functions that the convert-units package provides:

this.$units(12000).from('mm').to('m');
// 12 Metres

this.$units(12000).from('mm').toBest();
// 12 Meters (the smallest unit with a value above 1)

this.$units(12000).from('mm').toBest({ exclude: ['m'] })
// 1200 Centimeters (the smallest unit excluding meters)

this.$units(12000).from('mm').toBest({ cutOffNumber: 10 });
// 900 Centimeters (the smallest unit with a value equal to or above 10)

this.$units(12000)from('mm').toBest({ cutOffNumber: 10 })
// 10 Meters (the smallest unit with a value equal to or above 10)

this.$units(12000).from('m').possibilities();
// ["mm", "cm", "m", "km", "in", "yd", "ft-us", "ft", "mi"]

this.$units().measures();
// [ 'length', 'mass', 'volume' ]

For additional methods, please refer to the official repository for convert-units.

<script>
export default {
  props: {
      distance: {
          type: Number,
          default: 123456789
      }
  },
  computed: {
      shortDistance() {
          const obj = this.$units(this.distance).from('cm2').toBest({
              exclude: ['m2']
          });
          return `${obj.val} ${obj.unit}`;
      }
  }
}
