This converter turns a single duration into every other supported unit at once. Type a number, choose the unit it is in, and the full conversion table updates as you type. It covers seconds, minutes, hours, days and weeks. Each conversion goes through seconds as a common base, so results stay consistent no matter which unit you start from. It treats a day as exactly 24 hours and a week as exactly 7 days — fixed durations, not calendar dates. Everything runs in your browser and nothing you type is uploaded anywhere.
Common questions
How many seconds are in an hour?
One hour is 3,600 seconds. Enter 1 and select hour, and the results list shows the value in minutes, seconds, days and weeks at the same time.
How do I convert days to weeks?
Type your duration, select day as the unit, and read the week row. Seven days equals exactly one week in this tool.
Which units does this duration converter support?
Seconds (s), minutes (min), hours (h), days (d) and weeks (wk). Enter a value in any one and the rest are calculated instantly.
Does this account for months, leap years or daylight saving?
No. It converts fixed durations only, treating a day as 24 hours and a week as 7 days. It does not do calendar arithmetic, so it ignores months, leap years and daylight saving.
Are the values I type sent anywhere?
No. All conversions run entirely in your browser with JavaScript. Nothing you enter is uploaded or stored on a server.
