Convert between seconds, minutes, hours, days, and weeks.
Free to use, no sign-up required. Time Unit Converter is one of 198 tools built into Xenition, alongside a chat that can use them for you.
Converts durations between milliseconds, seconds, minutes, hours, days, weeks, months and years. Useful for turning a large number of seconds into days, or a project length in weeks into months.
Every unit is stored in seconds. A day is 86,400 s and a week 604,800 s. A year is the average Julian year of 365.25 days (31,557,600 s), and a month is one twelfth of that, 30.4375 days.
A million seconds is 11.574074 days. 90 days is 2.956879 months, because the average month here is 30.4375 days.
Calendar months run from 28 to 31 days. The tool uses the average month, 30.4375 days, so 3 months is 91.3 days. For a real calendar span between two dates, count the actual days.
365 in a common year and 366 in a leap year. Averaged over the four-year leap cycle that is 365.25, the value used here. The Gregorian calendar’s long-run average is 365.2425.

1 s is 1000 ms. To convert s to ms, divide by 0.001 — so 10 s is 10000 ms.
1 ms is 0.001 s. To convert ms to s, multiply by 0.001 — so 10 ms is 0.01 s.
1 s is 0.0166666667 min. To convert s to min, divide by 60 — so 10 s is 0.1666666667 min.
1 min is 60 s. To convert min to s, multiply by 60 — so 10 min is 600 s.
1 s is 0.0002777778 h. To convert s to h, divide by 3600 — so 10 s is 0.0027777778 h.
1 h is 3600 s. To convert h to s, multiply by 3600 — so 10 h is 36000 s.
1 s is 0.0000115741 day. To convert s to day, divide by 86400 — so 10 s is 0.0001157407 day.
1 day is 86400 s. To convert day to s, multiply by 86400 — so 10 day is 864000 s.
You do not have to open Time Unit Converter to use it. Ask Xenition in plain language and it runs the right tool, then carries the answer into whatever you are working on — a document, a spreadsheet, a deck.
