"According to Babidi, Majin Yakon's power level is 800 kili (a unit of measurement that is different from power levels displayed on the conventional scouters) - thus giving him enough power to destroy around four planets with one attack. As stated by Babidi, this is a level much weaker than Super Saiyan Goku's power level of 3,000 kili.
Since each unit of kili equals 50,000 the unit of scouters as stated by a 2004 V-Jump issue,[3] Majin Yakon's power level would be 40,000,000 if measured by a scouter."
