Dragonball Z Stated Power Levels

Specific power levels were only stated a few times in the Dragonball Z manga before Akira Toriyama decided it was too difficult to track them and keep them all making sense. Here is a list that shows when a power level is stated, along with the manga volume number, a relevant quote, and a supporting image (click on the image to see a full-size version in the gallery).

The previous power levels pages are still available:
