I just found it funny that on Wookieepedia, someone took a line from one of the Disney canon spinoff novels, and extrapolated from it that the sublight engines go several thousand times the speed of light. That felt like a good encapsulation of how much scientific sense Star Wars makes.
Also "megalight" should really equal one million light-something.
