Info about "Month"

A month forms the time span of 28, 29, 30 or 31 consecutive days. Due to its varying length, the month is not a physical unit of time and thus not a unit of time in the international SI system of units.

To enable a general conversion (e.g., into seconds, minutes or years), the average length of the month in days is defined: Since a year comprises 12 months, a normal calendar year with 365 days results in a month length of 365 / 12 = 30.416667 days

In astronomical terms, a month is defined as the period of one complete revolution of the moon. Depending on the definition, the lunar month is a little more than 28 days on average.

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 Month (mo) to Hour (h)

The abbreviation for the "Time unit Month" is mo. The abbreviation for the "Time unit Hour" is h.
