## How to Convert Seconds to Days

To convert a measurement in seconds to a measurement in days, divide the time by the following conversion ratio: 86,400 seconds/day.

Since one day is equal to 86,400 seconds, you can use this simple formula to convert:

days = seconds ÷ 86,400

The time in days is equal to the time in seconds divided by 86,400.

For example, here's how to convert 50,000 seconds to days using the formula above.
days = (50,000 s ÷ 86,400) = 0.578704 d

## What Is a Second?

The second has historically been defined as 1/60 of a minute or 1/86,400 of a day. According to the SI definition, the second is the duration of 9,192,631,770 oscillations of the frequency of light emitted from the atomic transition between the two hyperfine levels of the unperturbed ground state of the caesium 133 atom.[1]

The second is the SI base unit for time in the metric system. Seconds can be abbreviated as s, and are also sometimes abbreviated as sec. For example, 1 second can be written as 1 s or 1 sec.
