Conversion formula
How to convert 21 minutes to years?

We know (by definition) that: $1 \min \approx 1.9013259e-06 yr$

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

\frac{1 \min}{21 \min} \approx \frac{1.9013259e-06 yr}{x yr}

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

x yr \approx \frac{21 \min}{1 \min} * 1.9013259e-06 yr \to x yr \approx 3.99278439e-05 yr

Conclusion: $21 \min \approx 3.99278439e-05 yr$

21 minutes is equivalent to 3.99278434474586e-05 years

Conversion in the opposite direction

The inverse of the conversion factor is that 1 year is equal to 25045.1793449829 times 21 minutes.

It can also be expressed as: 21 minutes is equal to $\frac{1}{25045.1793449829}$ years.

Approximation

An approximate numerical result would be: twenty-one minutes is about zero years, or alternatively, a year is about twenty-five thousand and forty-five point one eight times twenty-one minutes.

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."

Years

"A year is the orbital in which Earth moves in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by changes in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the globe, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked."
