Could a proton torpedo fly faster than hypersonic missiles?

'Every' measurement we're use to is based on Earth. Would you prefer made up garbage like oBSG used where nobody knows what they actually mean?

With metres, you can sort of rationalise how they get there. It's requires some coincidence, but not too much.

Parsecs are specifically bound to Earth. You could say it's based around Coruscant's orbit and handwave it, but it's an odd leap.

Apparently, a Coruscant day is 24 hours and a Coruscant year is 365 days.

I wouldn't be surprised if a Coruscant parsec is the same as ours too, although the Wookieepedia doesn't cite a source that states it explicitly.

The only rational approach is just to consider it part of the translation along with why they are speaking English.

Otherwise you wind up with similar questions about language, which includes the question of what a falcon is and why X-wings and Y-wings use English letters in their names.
