divide by 60 to get minutes.
divide again by 60 to get hours.
divide by 24 to get days
as 60x60x24=86400, you can divide seconds by 86400 to convert straight to days.
The answer will depend on what it is that you are trying to combine!
there is 604,800 seconds in 7 days.
1 day = 86,400 seconds 2 days = 172,800 seconds 3 days = 259,200 seconds
53 days = 4 579 200 seconds
12583 seconds = 0.145636574 days
21 days = 1814400 seconds
650 days = 56160000 seconds
18 days = 1555200 seconds
There are 2,678,400 seconds in 31 days.
12,699 seconds is about 8.82 days.
240 days = 20,736,000 seconds.
200,000 seconds = 2.31481481 days.
