How to Convert Weeks to Seconds

To convert a measurement in weeks to a measurement in seconds, multiply the time by the following conversion ratio: 604,800 seconds/week.

Since one week is equal to 604,800 seconds, you can use this simple formula to convert:

seconds = weeks × 604,800

The time in seconds is equal to the time in weeks multiplied by 604,800.

For example, here's how to convert 5 weeks to seconds using the formula above.

seconds = (5 wk × 604,800) = 3,024,000 s

How Many Seconds Are in a Week?

There are 604,800 seconds in a week, which is why we use this value in the formula above.

1 wk = 604,800 s

Weeks and seconds are both units used to measure time. Keep reading to learn more about each unit of measure.

What Is a Week?

One week is a time period of seven days. The following days are a part of a week: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday.

Weeks can be abbreviated as wk (plural wks); for example, 1 week can be written as 1 wk, and 2 weeks can be written as 2 wks.

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.
