Conversion formula
How to convert 422 hours to years?

We know (by definition) that: 1 hr ≈ 0.00011407955 yr.

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

1 hr / 422 hr ≈ 0.00011407955 yr / x yr

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

x yr ≈ (422 hr / 1 hr) * 0.00011407955 yr → x yr ≈ 0.0481415701 yr

Conclusion:

422 hr ≈ 0.0481415701 yr

Conversion in the opposite direction

The inverse of the conversion factor is that 1 year is equal to 20.7720681771185 times 422 hours.

It can also be expressed as: 422 hours is equal to 1 / 20.7720681771185 years.

Approximation

An approximate numerical result would be: four hundred and twenty-two hours is about zero point zero five years, or alternatively, a year is about twenty point seven six times four hundred and twenty-two hours.

Units involved

This is how the units in this conversion are defined:

Hours

"Midnight (or noon) on a 12-hour analog clock An hour is a unit of time conventionally reckoned as 1⁄24 of a day and scientifically reckoned as 3,599–3,601 seconds, depending on conditions.The seasonal, temporal, or unequal hour was established in the ancient Near East as 1⁄12 of the night or daytime. Such hours varied by season, latitude, and weather. It was subsequently divided into 60 minutes, each of 60 seconds. Its East Asian equivalent was the shi, which was 1⁄12 of the apparent solar day; a similar system was eventually developed in Europe which measured its equal or equinoctial hour as 1⁄24 of such days measured from noon to noon. The minor variations of this unit were eventually smoothed by making it 1⁄24 of the mean solar day, based on the measure of the suns transit along the celestial equator rather than along the ecliptic. This was finally abandoned due to the minor slowing caused by the Earths tidal deceleration by the Moon.In the modern metric system, hours are an accepted unit of time equal to 3,600 seconds but an hour of Coordinated Universal Time (UTC) may incorporate a positive or negative leap second,[a] making it last 3,599 or 3,601 seconds, in order to keep it within 0.9 seconds of universal time, which is based on measurements of the mean solar day at 0° longitude."

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."
