Enter a duration, pick your units.
Type a time value, choose where it's converting from and to, and get an exact result — with an advanced mode for full precision control and a complete unit table.
Applies to the main result and the full unit table below.
Three fields, one result.
No manual required — here's the entire flow.
Enter your value
Type the time you want to convert into the value field. The tool starts you off with a value of 3600 (seconds).
Pick your units
Choose the unit you're converting from and the unit you want, or tap ⇅ to instantly swap the two.
Hit convert
Tap Convert and the exact result appears immediately in the results panel, right beside the tool.
Go further
Open Advanced options to adjust decimal precision or view your value converted into every supported unit at once.
Twelve units, exact factors, full control.
Every conversion uses fixed, standard-defined factors — never rough estimates.
Small & large units
The everyday time units, from milliseconds up to hours, all tied to the second as the base unit.
Calendar units
Includes the standard 365-day year and a 30.44-day average month, clearly labeled for accurate conversion.
Long-term units
Convert across decades, centuries, and millennia — useful for historical, geological, or planning contexts.
Questions people actually ask.
The short answers — with the long ones one tap away.
How do I convert seconds to minutes?+
Divide the number of seconds by 60 to get minutes. In this tool, set Convert from to Second and Convert to to Minute, or tap the 60 SEC → MIN quick-conversion chip.
What is the exact conversion factor between hours and days?+
One day is defined as exactly 24 hours. This tool uses that exact figure, along with the standard factors for minutes, seconds, weeks, and years, so results are accurate rather than rounded estimates.
How many seconds are in a year?+
A common year of 365 days contains 31,536,000 seconds. A leap year of 366 days contains 31,622,400 seconds. This tool uses the 365-day year as the default for "Year" and clearly labels the unit.
Can I see a value converted into every unit at once?+
Yes. Tap Show advanced under Advanced options and the results panel will display a full table converting your entered value into every supported unit at the same time.
Can I change how many decimal places are shown?+
Yes. Open Advanced options and choose a decimal precision from 0 to 8 places. It applies to both the main result and the full conversion table.
Is this time converter free, and does it work offline once loaded?+
It's completely free with no account or sign-up. All the math runs directly in your browser using fixed conversion factors — no data is sent anywhere, and no external service is called to perform a conversion.
