You can do the reverse unit conversion from millicentury to sidereal month, or enter any two units below:
The sidereal month is defined as the Moon's orbital period in a non-rotating frame of reference (which on average is equal to its rotation period in the same frame). It is about 27.32166 days (27 days, 7 hours, 43 minutes, 11.6 seconds). The exact duration of the orbital period cannot be easily determined, because the 'non-rotating frame of reference' cannot be observed directly. However, it is approximately equal to the time it takes the Moon to pass twice a "fixed" star (different stars give different results because all have proper motions and are not really fixed in position).
The SI prefix "milli" represents a factor of 10-3, or in exponential notation, 1E-3.
So 1 millicentury = 10-3 centuries.
The definition of a century is as follows:
A century is a period of 100 years, which can have either 24 or 25 leap years, depends on whether the year xx00 is a leap year or not.
We assume there are 25 leap year days in a typical century. A non-leap year of 365 days would have 86,400 * 365 = 31,536,000 seconds in it. Adding another 25 days adds 2,160,000 seconds, so there are a total of 3,155,760,000 seconds in a century that has 25 leap years.
