## How to Convert Decades to Seconds

To convert a measurement in decades to a measurement in seconds, multiply the time by the following conversion ratio: 315,569,520 seconds/decade.

Since one decade is equal to 315,569,520 seconds, you can use this simple formula to convert:

The time in seconds is equal to the time in decades multiplied by 315,569,520.

For example, here's how to convert 5 decades to seconds using the formula above.
seconds = (5 decades × 315,569,520) = 1,577,847,600 s

### How Many Seconds Are in a Decade?

There are 315,569,520 seconds in a decade, which is why we use this value in the formula above.

The decade is a time period of 10 years.

## 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.
