Parsecs are used in astronomy to measure enormous interstellar distances. A parsec is approximately 3.26 light-years or about 3.085×1016 m. Combining it with the "atto-" prefix yields attoparsec (apc), a conveniently human-scaled unit of about 3.085 centimeters (about 1 7/32 inches) that has no obvious practical use.
Interestingly, 1 attoparsec/microfortnight is nearly 1 inch/second (the actual figure is about 1.0043 inches per second, or approximately 2.55 cm/s).

Does this mean you are coming to visit me in two weeks?
I'm not entirely convinced that 1 attoparsec/microfortnight is nearly 1 inch/second is, in fact, "interesting"...I'll have to think about it for a bit.
You have such interesting posts.
I take it you're still liking your job.
but why do I care?
my head broke...
You have incorrectly labeled the "Anderson Family" blog as being Brad and Kim, it is actually Diana and Richard
Oops! That was the one I didn't check, 'cuz I thought I knew who the Andersons were.
