About This Tool
Why use Time Converter Tool?
Convert between seconds, minutes, hours, days and weeks. Useful when a duration is quoted in one unit and you need it in another — a 5,400-second video is 90 minutes, and a 72-hour deadline is three days.
Time is one of the few systems that is not decimal: 60 seconds to a minute, 60 minutes to an hour, 24 hours to a day. That is why 1.5 hours is 90 minutes rather than 150, a mistake that turns up constantly in timesheets and invoices.

Time Converter Tool FAQs
How many seconds are in an hour?
3,600 — 60 minutes of 60 seconds. A day has 86,400 seconds.
How do I convert minutes to hours?
Divide by 60. 90 minutes is 1.5 hours and 45 minutes is 0.75 hours.
How many hours are in a week?
168 hours — 24 × 7. A standard full-time working week is 37.5 to 40 of them.

Because the decimal is a fraction of 60, not of 100. The 0.5 means half an hour, which is 30 minutes.
