Time Duration Converter
Convert between seconds, minutes, hours, and days.
Durations, converted
Time spans convert on fixed factors: 90 minutes is 1.5 hours, and 86,400 seconds make a day. This moves a duration between seconds, minutes, hours, and days.
It is handy for reading a video length in minutes as a fraction of an hour, converting a timeout set in seconds into something human, or summing durations for a schedule.
Not calendar dates
This handles elapsed time, not calendar arithmetic where months and leap years vary. Your values stay in the browser and are never uploaded.
Frequently Asked Questions
How does the time duration converter work?
Durations convert through seconds. Ninety minutes is 5,400 seconds, which becomes 1.5 hours.
When should I use this converter?
Use it when logs, estimates, subscriptions, audio lengths, or engineering tasks mix seconds, minutes, hours, and days.
What is the main limitation?
Months and years use average calendar lengths, so exact calendar math should use a date calculator.
Is this converter private?
Yes. The conversion runs entirely in your browser, so your values are not uploaded, stored, or sent to a server.
