Babidi first mentioned this unit when he and his right-hand man Dabura are collecting energy to awaken Majin Buu from his Sealed Ball. It is different from the energy unit measured on scouters; kili are measured by Power Meters different from the scouters and 1 Kili = 50,000 BP according to a 2004 V-Jump issue.
The only recorded kili measurements are 800, which belongs to Yakon, and 3,000, which belongs to Super Saiyan Goku. In the anime only, Dabura states that even a kili of 4,000 cannot defeat him, implying that he has a kili of over 4,000.
In Dragon Ball Xenoverse, Time Breakers Towa and Mira travel through time to seek warriors with powerful Kili and steal their energy and plan to use the accumulated stolen energy to break the seal on Demon Realm.
- Although a Kili is supposedly worth 50,000 BP, this is seemingly inconsistent with events in the series. Vegeta claims to be able to destroy a planet in his first fight with Goku, even though his power was only 18,000, or 0.36 of a Kili at the time (this is shown to be true when he destroys Arlia in anime filler). Frieza also destroyed a planet in his first form with only his finger, despite his power being 530,000, well below the 15 million (300 kilis) required to destroy a planet. Howevever "destroying" the planet could refer to annihilating it with a single attack, whereas Frieza destroyed a planet by detonating it's core.
- Given its usage by several denizens of Demon Realm (Babidi, Dabura, Towa, and Mira) it may be a common unit of measurement for power levels in Demon Realm.
- Goku's energy being measured at 3000 kili seems inconsistent, as if one kili truly is equal to 50000 in scouter units, that would only put his power level at 150000000, the same as it was against Frieza, and Goku had grown much stronger since then. However, it is very likely that Goku was not using his full power in Super Saiyan form when Babidi measured him, as Goku only transformed to light up the surroundings so he could see Yakon, and he didn't really seem to need it anyway, as he could sense Yakon's ki and smell where he was anyway, and Vegeta commented that Goku was already winning the fight in his base form. If 3000 kili truly was Goku's maximum power in Super Saiyan form, that would put his base form at only 60 kili, which seems almost impossible given how well Goku was faring against Yakon.
