Here you can convert the Time unit Year into the unit Hour and vice versa you can convert Hour into Year. By clicking the "Swap units" icon, you will always obtain the desired conversion in the calculation result, i.e., yr to h or h to yr. With the following calculator you can also calculate any other Time unit.
Info about "Year"
A year (a) (Latin: annus) forms the time span of 365 days, or in the case of a leap year, 366 consecutive days. Due to its varying length, the year is not a physical unit of time and thus not a unit of time in the international SI system of units.
In the time unit converter, a year is always calculated to be 365 days.
In astronomical terms, a year is defined as the duration of the Earth’s orbit around the Sun, which lasts 365.25 days on average. Due to the quarter of a day, a normal calendar year (common year) is defined as 365 days, which is replaced every four years by a leap year with 366 days.
In everyday life, the term "year" is understood to mean the period from 1st January to 31st December.
Info about "Hour"
The hour (h) (Latin: hora) is not part of the International SI System of Units, but it is permitted for use with the SI. The hour is derived from the base unit second. This makes it a legal unit of measurement.
Here, 1 hour is equal to 3,600 seconds or 1 second is equal to 0.00027778 hours (3,600ths).
For thousands of years—before the hour was officially defined as 3,600 times a second—it was considered the 24th part of a day. But how did the day originally change to a division of the day into 24 hours? In ancient Egypt, sundials were used to divide the day into 24 hours based on the common system (duodecimal system) at the time. The twelve-unit system may have originated historically from the fact that one individual finger links (three links per finger without thumb) were used for counting. Of course, sundials could not be used at night, so the Egyptians used the course of 12 stars to divide the night into 12-time units. This means that even today, the day still has 24 hours.
The hour was only reverted to the basic unit of the second in the middle of the 20th century after it was established and the astronomical day or one revolution of the Earth, was becoming shorter and shorter, albeit only minimally. At the same time, quartz clocks were able to measure time more accurately, making the second the basic unit. To synchronise the present accurate atomic clocks with the duration of the earth's rotation, a leap second had to be inserted every 2 to 5 years for one hour to make 3,601 seconds.
Basis for conversion Year (yr) to Hour (h) and vice versa
The abbreviation for the "Time unit Year" is yr. The abbreviation for the "Time unit Hour" is h.
