Time Unit Converter
Seconds, minutes, hours, days, weeks.
The time unit converter translates durations between milliseconds, seconds, minutes, hours, days, and weeks. Type a value into any field and the other units update instantly.
This is handy for all kinds of tasks: converting timeouts and delays from milliseconds to seconds during development, figuring out how many hours are in a work week, estimating the length of a process or video, or turning large intervals into more familiar units. Reference points: 1 minute = 60 s, 1 hour = 3600 s, 1 day = 86,400 s, 1 week = 604,800 s.
Calculations go through seconds as the base unit, so any pair converts precisely. Note that this converts durations (intervals), not dates — to find the difference between two calendar dates, use a date calculator instead. Everything is calculated right in your browser, with no data sent anywhere.
