The size of the sac is a computer measurement. The role of a human being is to mark the limits of the sac with a cursor.
The patient conceives 14 days after the LMP (that is also the time of Ovulation). And the computer is programmed to pick up the size from the date of conception .
Hence a difference of two weeks.
As the pregnancy progresses there is some error in measurement. The bigger the pregnancy, the more the error.
