Throughout the vast expanse of the galaxy, numerous systems for measuring different quantities have been developed and utilized.
- DPF: A metric quantifying the agility of a starfighter. [1]
- PH [2]

Despite the utilization of US/Imperial measurements, like the foot and the inch, in certain Star Wars materials, the franchise predominantly employs the metric system. Editor Tom Hoeler even made a decision to avoid using the term "inching" while promoting the novel The Living Force on Twitter due to this preference, acknowledging that it might be "a ridiculous line of thought" for a simple social media post. Hoeler further mentioned that editors would identify instances of the Imperial system and replace them with the metric system. However, Hoeler admitted that Star Wars creatives have never successfully created a metric equivalent of "inching closer," with author John Jackson Miller even joking about the absence of the phrase "centimetering ever closer."
