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 millifortnight = 10-3 fortnights.
The definition of a fortnight is as follows:
A fortnight is a unit of measurement of time equal to two weeks: that is 14 days, or literally 14 nights. The term is most commonly used in British English. It derives from the Old English feowertiene niht, meaning "fourteen nights".
