Number of Seconds in a Day

There are 86,400 Seconds in a day. How do you calculate this? Well, it's pretty easy!

A day is a unit of time that represents one complete rotation of the Earth around its axis. It is divided into 24 hours. Each hour is made up of 60 minutes. Each minute is made up of 60 seconds. So, to find the number of seconds in one day, we need to multiply the number of seconds in one hour by the number of hours in a day.

Seconds in one day = Seconds per minute (60) × Minutes per hour (60) × Hours per day (24) = 86,400 Seconds.

What about the calculator?

This calculator is a time conversion tool. ⌚

It allows you to convert between different units of time, ranging from very small units like picoseconds (one trillionth of a second) to very large units like a millennium (a thousand years).

Please Note: The calculator assumes 30-Day Months, and 365-Day Years. (Not 28 or 31 Days).

Here's how it works:

0_Seconds_Day_Image

You enter a number in one of the two input fields. (This is the amount of time you want to convert). Then select the corresponding time unit from the dropdown under it.

The other input field and dropdown menu will automatically update to show the converted value in the selected time unit under it.
