SK was a unit of measurement of computer data. A Swift 78B Vessel Courier System, a skull implant that could be used to carry sensitive information, could hold 800 SKs of memory.
During the Galactic Civil War, the group of renegade slicers known as the Skaak Tippers took the first part of their name from a combination of the SK unit of measure and the aak dog, an animal native to the planet Haruun Kal. "Tipper," the founder of the group, believed the word made the Skaak Tippers sound like vicious computer hackers.
The SK unit of measure was first mentioned in the 1991 sourcebook Cracken's Rebel Field Guide, a supplement for Star Wars: The Roleplaying Game published by West End Games.
