The conversion factor from weeks to days is 7, which means that 1 week is equal to 7 days:

1 wk = 7 d

To convert 1990 weeks into days we have to multiply 1990 by the conversion factor in order to get the time amount from weeks to days. We can also form a simple proportion to calculate the result:

1 wk → 7 d

1990 wk → T_(d)

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

T_(d) = 1990 wk × 7 d

T_(d) = 13930 d

The final result is:

1990 wk → 13930 d

We conclude that 1990 weeks is equivalent to 13930 days:

1990 weeks = 13930 days

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.

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.
