1 day has 86,400 seconds.
Seconds in a day calculation
We know that 1 day is 24 hours.
1 hour is 60 minutes.
And we know that 1 minute is 60 seconds.
So if we multiply all that through, we have:
= 24 hours per day x 60 minutes per hour x 60 seconds per minute
= 86,400 seconds per day (86,400 seconds per 24-hour day)
Of course, now that you know that there are 86,400 seconds in 24 hours, you can calculate how many seconds there are…
– per week
– per year
– per century…
…and virtually every other expanse of time.
