How do you convert 3secs. into days?
Is there a typo here?
You meant 3 seconds?
There are 24 hours in one day.
60 minutes = 1 hour.
60 seconds = 1 minute.
How many minutes in one day?
60 x 24 = 1440 minutes in one day.
How many seconds in one day?
1440 x 60 = 86,400 seconds in one day.
How does this relate to your question is a mystery to me.
