Power Levels (Relevant in early chapters)

Sadalla remembered the old power system that had initially been used by saiyans and the Frieza Force. It didn't have much meaning, but Sadalla knew there were a few basic benchmarks:

A power level of 1 meant basically no strength. Even a very weak punch from a saiyan infant could kill you. 

A power level of 10 was considered extremely weak. You could destroy at most a few cities or a small country.

A power level of 100 was where things got serious. The old master Roshi on Earth could blow up the moon at this power level. Earth's moon is on the scale of a very small planet, a little above half of the size of Mercury, the smallest planet in Earth's Solar System.

Power at 1000 was capable of destroying most gas giants, but their gravity may pull them back together. Even at their peak, no one on Earth could clear this benchmark until after the saiyan Raditz had invaded.

Once you reached 10,000, there was no question. Only a handful of the strongest saiyans could reach this level. Small white dwarf stars would be threatened by your power, and at 100,000 you might destroy a red dwarf star completely. No saiyan on Planet Plant had ever reached this strength threshold.

Upon reaching 1,000,000, you could blow up even the medium-sized stars like Sol. Only beings like Frieza or King Cold could surpass this. Until Goku, at least, where this was just a threshold.

Ten million. That was the benchmark. Large stars and neutron stars came under threat. Frieza himself had only reached 60,000,000, and King Cold was behind even that.

Lastly, there was 100,000,000. Only the largest stars remained outside of your grasp. Feats beyond the speed of light became possible, and small solar systems could be blasted from existence. No power levels existed beyond this because technology couldn't detect them. Any being at that level could declare themselves a god, and only the gods themselves would contest it.
