• To convert 3 hours 5 minutes and 10 seconds into a number of seconds, select 03:05:10 in the "Duration" field then click on the "Ok" button. The conversion into a number of seconds will be displayed automatically, i.e. 11110 seconds
• To convert 4587 seconds into duration, enter 4587 in the "Second(s)" field and its conversion into duration will be automatically displayed, i.e. 01:16:27 (1h16m27s)
In order to calculate the number of seconds from a duration, simply use the following formula:
(Hours * (60 * 60)) + (Minutes * 60) + Seconds = Seconds
Example : for 14:05:19, i.e. 14 hours, 5 minutes and 19 seconds, the number of seconds will be 50719:
(14 * (60 * 60)) + (5 * 60) + 19 = 50719
