I’ve finished Chain of Attack. Enjoyable old-skool Trek novel, despite extreme overuse of the word “parsec” (they could have said "3.7 light-years" just once)
But the reason astronomers prefer the parsec is because the parralax is the way the find the distance of stars, thus making it a very nice and logical unit. In Trek I'm almost certain they don't use parralax to measure distance, and thus it would be more logical to use lightyears, or to express the distance in kilometres.I’ve finished Chain of Attack.

Well, first off, why use six syllables when two will do? Second, a parsec is 3.26 light-years. Third, as I remarked the last time you brought this up, the parsec is the standard formal unit of astronomical distance, whereas "light-year" is more of a vernacular term. Astronomers and astrophysicists use parsecs more than they use light-years; most likely they only use light-years when talking to the general public. Thus it stands to reason that professional starfarers, and particularly science officers, would preferentially use parsecs as well.
...or to express the distance in kilometres.
10 Petametres....or to express the distance in kilometres.
That one might be a bit unwieldy.
1ly approx 9460528400000 km!

It would be more logical, though.10 Petametres.That one might be a bit unwieldy.

indeed.Then people'd be complaining that authors are using uncommon units of measurement, and we'd be back to the parsec.

I've decided that in my next story, I will somehow work in the term "stygian petametre".10 Petametres.That one might be a bit unwieldy.

Sure, it would still work, but why wait half a year to find out a star's distance when you can send a ship there in a few weeks and find out the distance like that?But the reason astronomers prefer the parsec is because the parralax is the way the find the distance of stars, thus making it a very nice and logical unit.

Why wouldn't they use parallax? If it works today, it will work 300 or a thousand or a million years from now. New technologies usually coexist alongside old ones rather than replacing them completely.
