How to use it:
1. Install & import the Convert.
# Yarn
$ yarn add convert
# NPM
$ npm i convert
// ES Module
import convert from 'convert';
// CommonJS
const {convert} = require('convert');
// Browser
<script src="https://cdn.jsdelivr.net/npm/convert@4/dist/convert.prod.js"></script> 2. Convert a unit to another.
convert(480, 'seconds').to('minutes');
// -> 8
convert(20n, 'hours').to('minutes');
// -> 1200n
convert(6600, 'meters').to('best');
// -> { quantity: 6.6, unit: 'km', toString: () => '6.6km' }
convert(3.5, 'km').to('best', 'imperial');
// -> { quantity: 2.17, unit: 'mi', toString: () => '3.5mi' } 3. Convert multiple units.
// ES Module
import {convertMany} from 'convert';
// CommonJS
const {convertMany} = require('convert'); convertMany('1d 12h').to('hours')
// -> 95400000 4. Convert a given duration of milliseconds to a string.
// ES Module
import {ms} from 'convert';
// CommonJS
const {ms} = require('convert'); ms(-3 * 60000);
// -> '-3min'
ms('1d 2h 30min');
// -> 95400000 Changelog:
v5.1.0 (04/12/2025)
- angle: add arcminutes and arcseconds units
