# ms[](https://travis-ci.org/zeit/ms)[](https://zeit.chat/)Use this package to easily convert various time formats to milliseconds.## Examples```jsms('2 days') // 172800000ms('1d') // 86400000ms('10h') // 36000000ms('2.5 hrs') // 9000000ms('2h') // 7200000ms('1m') // 60000ms('5s') // 5000ms('1y') // 31557600000ms('100') // 100```### Convert from milliseconds```jsms(60000) // "1m"ms(2 * 60000) // "2m"ms(ms('10 hours')) // "10h"```### Time format written-out```jsms(60000, { long: true }) // "1 minute"ms(2 * 60000, { long: true }) // "2 minutes"ms(ms('10 hours'), { long: true }) // "10 hours"```## Features- Works both in [node](https://nodejs.org) and in the browser.- If a number is supplied to `ms`, a string with a unit is returned.- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`).- If you pass a string with a number and a valid unit, the number of equivalent ms is returned.## Caught a bug?1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device2. Link the package to the global module directory: `npm link`3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, node will now use your clone of ms!As always, you can run the tests using: `npm test`
