Conversion formula
How to convert 657 seconds to weeks?

We know (by definition) that: $1 \sec \approx 1.6534392e-06 wk$

We can set up a proportion to solve for the number of weeks.

\frac{1 \sec}{657 \sec} \approx \frac{1.6534392e-06 wk}{x wk}

Now, we cross multiply to solve for our unknown $x$ :

x wk \approx \frac{657 \sec}{1 \sec} * 1.6534392e-06 wk \to x wk \approx 0.0010863095544 wk

Conclusion: $657 \sec \approx 0.0010863095544 wk$

657 seconds is equivalent to 0.00108630952380952 weeks

Conversion in the opposite direction

Units involved

This is how the units in this conversion are defined:

Seconds

"The second (symbol s) is the base unit of time in the International System of Units. It is qualitatively defined as the second division of the hour by sixty, the first division by sixty being the minute.[3] SI definition of second is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom. Seconds may be measured using a mechanical, electrical or an atomic clock. SI prefixes are combined with the word second to denote subdivisions of the second, e.g., the millisecond (one thousandth of a second), the microsecond (one millionth of a second), and the nanosecond (one billionth of a second). Though SI prefixes may also be used to form multiples of the second such as kilosecond (one thousand seconds), such units are rarely used in practice. The more common larger non-SI units of time are not formed by powers of ten; instead, the second is multiplied by 60 to form a minute, which is multiplied by 60 to form an hour, which is multiplied by 24 to form a day. The second is also the base unit of time in other systems of measurement the centimetre–gram–second, metre–kilogram–second, metre–tonne–second, and foot–pound–second systems of units."

Weeks

"A week 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."
