How to Convert Weeks to Days

To convert a measurement in weeks to a measurement in days, multiply the time by the following conversion ratio: 7 days/week.

Since one week is equal to 7 days, you can use this simple formula to convert:

days = weeks × 7

The time in days is equal to the time in weeks multiplied by 7.

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

days = (5 wk × 7) = 35 d

How Many Days Are in a Week?

There are 7 days in a week, which is why we use this value in the formula above.

1 wk = 7 d
