Conversion formula
How to convert 21 minutes to months?

We know (by definition) that: $1 \min \approx 2.2815911e-05 mo$

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

\frac{1 \min}{21 \min} \approx \frac{2.2815911e-05 mo}{x mo}

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

x mo \approx \frac{21 \min}{1 \min} * 2.2815911e-05 mo \to x mo \approx 0.000479134131 mo

Conclusion: $21 \min \approx 0.000479134131 mo$

21 minutes is equivalent to 0.000479134121369504 months

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."

Months

"A month is a unit of time, used with calendars, which is approximately as long as a natural period related to the motion of the Moon; month and Moon are cognates. The traditional concept arose with the cycle of moon phases; such months (lunations) are synodic months and last approximately 29.53 days. From excavated tally sticks, researchers have deduced that people counted days in relation to the Moons phases as early as the Paleolithic age. Synodic months, based on the Moon s orbital period with respect to the Earth-Sun line, are still the basis of many calendars today, and are used to divide the year."
