Time Unit Converter
Convert milliseconds, seconds, minutes, hours, days, and weeks. 1 second = 1000 milliseconds. 1 minute = 60 seconds. 1 hour = 60 minutes. 1 day = 24 hours. 1 week = 7 days. Seconds are the internal base. Months and years are not included because calendar months and years vary in length. This tool does not treat every month as 30 days or every year as 365 days.

Quick examples
Why months and years are omitted
February can have 28 or 29 days. Civil years can have 365 or 366 days. Treating those as fixed conversion units would silently invent a duration. Use a calendar tool for date arithmetic; use this page for fixed clock durations.
