ms

Use this package to easily convert various time formats to milliseconds.

Examples

1toMs('2 days')  // 172800000
2toMs('1d')      // 86400000
3toMs('10h')     // 36000000
4toMs('2.5 hrs') // 9000000
5toMs('2h')      // 7200000
6toMs('1m')      // 60000
7toMs('5s')      // 5000
8toMs('1y')      // 31557600000
9toMs('100')     // 100
10toMs('-3 days') // -259200000
11toMs('-1h')     // -3600000
12toMs('-200')    // -200

Convert from Milliseconds

1fromMs(60000)             // "1m"
2fromMs(2 * 60000)         // "2m"
3fromMs(-3 * 60000)        // "-3m"
4fromMs(toMs('10 hours'))    // "10h"

Time Format Written-Out

1fromMs(60000, { long: true })             // "1 minute"
2fromMs(2 * 60000, { long: true })         // "2 minutes"
3fromMs(-3 * 60000, { long: true })        // "-3 minutes"
4fromMs(toMs('10 hours'), { long: true })    // "10 hours"
