How Many Weeks Is 7 Days?

Conversion formula

The conversion factor from days to weeks is 0.14285714285714, which means that 1 day is equal to 0.14285714285714 weeks:

1 d = 0.14285714285714 wk

To convert 7 days into weeks we have to multiply 7 by the conversion factor in order to get the time amount from days to weeks. We can also form a simple proportion to calculate the result:

1 d → 0.14285714285714 wk

7 d → T_(wk)

Solve the above proportion to obtain the time T in weeks:

T_(wk) = 7 d × 0.14285714285714 wk

T_(wk) = 1 wk

The final result is:

7 d → 1 wk

We conclude that 7 days is equivalent to 1 weeks:

7 days = 1 weeks

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 week is equal to 1 × 7 days.

Another way is saying that 7 days is equal to 1 ÷ 1 weeks.

Conversion units

The units involved in this conversion are days and weeks. This is how they are defined:

Day

A day (symbol: d) is a unit of time. In common usage, it is either an interval equal to 24 hours or daytime, the consecutive period of time during which the Sun is above the horizon. The period of time during which the Earth completes one rotation with respect to the Sun is called a solar day. Several definitions of this universal human concept are used according to context, need and convenience. In 1960, the second was redefined in terms of the orbital motion of the Earth, and was designated the SI base unit of time. The unit of measurement "day", redefined in 1960 as 86 400 SI seconds and symbolized d, is not an SI unit, but is accepted for use with SI. A civil day is usually 86 400 seconds, plus or minus a possible leap second in Coordinated Universal Time (UTC), and occasionally plus or minus an hour in those locations that change from or to daylight saving time.

Week

A week (symbol: wk) is a time unit equal to seven days. It is the standard time period used for cycles of rest days in most parts of the world, mostly alongside—although not strictly part of—the Gregorian calendar. The days of the week were named after the classical planets (derived from the astrological system of planetary hours) in the Roman era. In English, the names are Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday.
