How it works

For durations rather than calendar dates: how many hours a project took, how many minutes are in a shift, how many seconds a process is allowed to run.

Result = Value × (Factor of source unit ÷ Factor of target unit), in seconds

Example: A 90-minute film is 1.5 hours or 5,400 seconds. A 40-hour week is 2,400 minutes.

Questions people ask

How are months and years counted here?

A month is treated as 30 days and a year as 365 days, which is the convention for durations. For exact calendar gaps use the time between dates calculator.

How many seconds are in a day?

86,400 — 24 hours of 60 minutes of 60 seconds. Leap seconds occasionally add one, but they are not used in everyday calculations.

How do I convert decimal hours into hours and minutes?

Multiply the decimal part by 60. 7.25 hours is 7 hours and 15 minutes.
