How It Works
Converting from seconds to days requires understanding the relationship between these two time units.
Conversion Formula:
1 day = 24 hours = 1,440 minutes = 86,400 seconds
To convert seconds to days, divide the number of seconds by 86,400:
Days = Seconds ÷ 86,400
Example Calculations:
To convert 3,600 seconds to days:
Days = 3,600 seconds ÷ 86,400 = 0.041666667 days
To convert 172,800 seconds to days:
Days = 172,800 seconds ÷ 86,400 = 2 days
Our converter handles this calculation automatically and provides results with up to 9 decimal places for precision. It also formats the result to remove unnecessary trailing zeros for better readability.

How many seconds are in a day?
There are exactly 86,400 seconds in one day. This is calculated as follows:
- 1 day = 24 hours
- 24 hours × 60 minutes/hour = 1,440 minutes
- 1,440 minutes × 60 seconds/minute = 86,400 seconds
How accurate is this converter?
Our converter uses the exact conversion factor of 86,400 seconds = 1 day, which is the standard time conversion for a 24-hour day. The calculator can display results with up to 9 decimal places for high precision needs. Note that this conversion assumes a standard 24-hour day and does not account for leap seconds or daylight saving time changes.
