How to convert 21 minutes to weeks?

We know (by definition) that: 1 min ≈ 9.9206349e-05 wk.

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

1 min / 21 min ≈ 9.9206349e-05 wk / x wk

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

x wk ≈ (21 min / 1 min) * 9.9206349e-05 wk → x wk ≈ 0.002083333329 wk

Conclusion:

21 min ≈ 0.002083333329 wk

Conversion in the opposite direction

Units involved

This is how the units in this conversion are defined:

Minutes

"The minute is a unit of time or of angle. As a unit of time, the minute is equal to 1⁄60 (the first sexagesimal fraction) of an hour, or 60 seconds. In the UTC time standard, a minute on rare occasions has 61 seconds, a consequence of leap seconds (there is a provision to insert a negative leap second, which would result in a 59-second minute, but this has never happened in more than 40 years under this system). As a unit of angle, the minute of arc is equal to 1⁄60 of a degree, or 60 seconds (of arc). Although not an SI unit for either time or angle, the minute is accepted for use with SI units for both. The SI symbols for minute or minutes are min for time measurement."

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."
