Weeks to Days Converter

What this converter does

This turns a number of weeks into days. It is about as straightforward as conversions get, since a week is simply 7 days. Enter the weeks and the days come straight back, with decimals handled if you enter a part-week.

How to use it

1. Enter Weeks. Type the number of weeks.

Press Calculate and the equivalent in days appears.

How the conversion works

There are 7 days in a week, so to convert weeks to days you multiply by 7. So 1 week is 7 days, 3 weeks is 21, and 2 weeks is 14. The number grows because a day is the smaller unit, and the relationship is exact, since a week is always exactly 7 days with no variation.

When weeks into days helps

Weeks are a comfortable way to talk about a plan, but a lot of practical counting happens in days. Working out a deadline a few weeks out, counting down to something, or lining a weekly figure up against a day-based schedule all become easier once the weeks are in days. A 3 week lead time is clearer as 21 days when you are marking it on a calendar.

An example

Take 3 weeks. Multiply by 7 and you have 21 days. Two weeks is 14 days, and 6 weeks is 42. A part-week shows as the decimal, so 1.5 weeks is 10.5 days.
