+# pretty-ms [![Build Status](https://travis-ci.org/sindresorhus/pretty-ms.svg?branch=master)](https://travis-ci.org/sindresorhus/pretty-ms)
+
+> Convert milliseconds to a human readable string: `1337000000` → `15d 11h 23m 20s`
+
+
+## Usage
+
+```
+$ npm install --save pretty-ms
+```
+
+```js
+var prettyMs = require('pretty-ms');
+
+prettyMs(1337000000);
+//=> '15d 11h 23m 20s'
+
+prettyMs(1337);
+//=> '1.3s'
+
+prettyMs(133);
+//=> '133ms'
+
+// compact option
+prettyMs(1337, {compact: true});
+//=> '~1s'
+
+// verbose option
+prettyMs(1335669000, {verbose: true});
+//=> '15 days 11 hours 1 minute 9 seconds'
+
+// can be useful for time durations
+prettyMs(new Date(2014, 0, 1, 10, 40) - new Date(2014, 0, 1, 10, 5))
+//=> '35m'
+```
+
+
+## API
+
+### prettyMs(milliseconds, [options])
+
+#### milliseconds
+
+*Required*  
+Type: `number`
+
+Milliseconds to humanize.
+
+#### options
+
+##### secDecimalDigits
+
+Type: `number`  
+Default: `1`
+
+Number of digits to appear after the seconds decimal point.
+
+##### msDecimalDigits
+
+Type: `number`  
+Default: `0`
+
+Number of digits to appear after the milliseconds decimal point.
+
+Useful in combination with [`process.hrtime()`](https://nodejs.org/api/process.html#process_process_hrtime).
+
+##### compact
+
+Type: `boolean`  
+Default: `false`
+
+Only show the first unit: `1h 10m` → `~1h`.
+
+##### verbose
+
+Type: `boolean`  
+Default: `false`
+
+Use full-length units: `5h 1m 45s` → `5 hours 1 minute 45 seconds`
