If you want to determine the number of seconds that make up a day, you have to start by calculating the smallest time measurement unit. There are 60 seconds in one minute and 60 minutes make up one hour. Since there are 24 hours in a day, we first calculate the number of seconds in one hour and then multiply the value by 24 hours.
The calculation can be expressed as;
1 minute = 60 seconds
60 minutes = 1 hour
24 hours = 1 day
Actual Number Of Seconds In A Day
Therefore, 60 seconds x 60 minutes = 3,600 seconds, which is equivalent to 1 hour.
Since one day has 24 hours, you will multiply the number of seconds in one hour by the number of hours in one day. It is expressed as;
1 hour = 3,600 seconds
1 day = 3600 seconds x 24 hours = 86400 seconds/ day
Hence 86,400 seconds are in one day.
A second is a standard unit of measuring time used and widely recognized by the International System of Units. An hour is also used to measure time and is equivalent to 1/24 of solar day or measured exactly as 3600 seconds. The word ‘second' was derived from a Latin word meaning ‘the second division of hours'. It is also the basic reference unit for precise units of time measurement such as milliseconds, microseconds and nanoseconds.
The Scientists in Ancient Egypt came up with the idea of dividing one solar day into 24 equal parts. It is widely used today as a unit of measurement and extensively used in science. It also defines various related units for measuring time such as ampere per hour, kilowatt per hour, kilometers per hour etc.
How to convert seconds to days
There is a simple formula used if you want to convert second to days. We divide the number of seconds by 86,400 to get the number of days.
Days = seconds ÷86,400
Exact Number Of Seconds In A Day
For example, Convert 98,400 seconds to days
Solution
If 1 day = 86,400 seconds
? Days = 98,400 seconds?
= 98,400 / 86,400
= 1.138889 days
You can also use the Seconds to Day converter as it gives the corresponding values in days when converting from seconds.

How to Convert Seconds to Time in Excel
If you want to convert a number of seconds to a time in Excel, the easiest way is to:
- Divide the number of seconds by 86400 (the number of seconds in a day);

Format a cell as a time by selecting the 'Time' option from the drop-down menu on the ribbon
This method of converting a number of seconds to a time works because dates and times in Excel are stored as simple decimal values, with one day represented by the decimal value 1.0, and one second represented by the decimal value 1/86400 (i.e. 1.0 divided by the number of seconds in a day).
Therefore, any number of seconds can be converted into an Excel time using the formula:

Formatting Cells to Display Times in Excel
If the result of your time calculation is displayed as a decimal, you need to set the cell's formatting to an Excel time format. This can be done using one of the following methods:
Method 1 - Formatting Through the Ribbon Options
The easiest way to change cell formatting to a simple 'Time' format is to select the cell(s) to be formatted and then select the Time option from the drop-down menu in the ribbon. This is found in the 'Number' group on the Home tab (see below):
Method 2 - Formatting Through the 'Format Cells' Dialog Box
If you require a greater selection of time formats, you may prefer to apply cell formatting using the 'Format Cells' dialog box:
- Select the cell(s) to be formatted;
- Open up the 'Format Cells' dialog box by either:
- Clicking on the dialog box launcher in the 'Number' grouping, on the Home tab of the Excel ribbon (see rightabove).
- Using the keyboard shortcut Ctrl + 1 (i.e. press the Ctrl key and while holding this down press 1).
- Ensure the Number tab of the 'Format Cells' dialog box is selected;
- From the Category: list, select the option Time.(If you want a time other than the default, you can then select one of the options from the list on the right hand side of the 'Format Cells' dialog box).
- Click OK to apply the formatting and close the dialog box.

Formatting Cells to Display More Than 24 Hours
It is likely that the standard time format (applied when you use the ribbon option to format a time) will only display times up to 24 hours.
However, If you use the 'Format Cells' dialog box to format your cell(s), when you select the Time option from the 'Categories:' list, a further 'Type' list will appear on the right hand side of the dialog box (shown below).
From within the 'Type' list, select a time format that displays an hour value that is greater than 24, before clicking on the OK button, to close the dialog box.
