Power Levels

Dragonball Z Movies & Specials
Bardock Special
Bardock: 8,000
Toma: 6,000
Ozouru Bardock: 80,000
Ozouru Toma: 60,000
Chibi Vegeta: 5,000
Bardock (on Planet Meet): Close to 10,000
Kakarotto as a baby: 2
Dudoria's Henchmen on Planet Meat: < 8,000
Dudoria: Anywhere from 10,000 to 21,000
Furiza: 530,000
Since Bardock's level is just under 10,000 before visiting planet Meet, its probably around 8,000 at the begining. This, in turn, means Toma is weaker than Bardock since he was unable to kill Bardock's attacker. A Saiya-jin in Ozouru form is 10x stronger than a Saiya-jin in normal form which gives us Ozouru Bardock and Ozouru Toma.

Chibi Vegeta is probably around 5,000 since he easily defeats 10 saibamen, which have PLs of 1,200 each. Bardock easily defeat's Dudoria's men, but gets his butt kicked by Dudoria. Furiza probably has the same level here as in the Namek saga.
Trunks Special
Android 17: 20,000,000
Android 18: 20,000,000

SSj Gohan: 25,000,000
SSj Trunks: 17,000,000
Here, the Android's power levels are based on the fact that Trunks states that the Androids from this timeline are much weaker than the ones he encounters in the main timeline. Since Gohan can take on one of them, but falters when fighting both of them, Gohan probably has around 25,000,000.

Trunks' level is based on the level he has when arriving on Earth to fight Furiza bot.
Dragonball Z Episodes

Farmer with Shotgun: 5
 
Saiya-jin Saga: Raditsu Vs. Goku and Piccolo
Raditsu: 1,200
Piccolo (with weighted clothing) : 322
Piccolo (without weighted clothing) : 408
Piccolo's Makankosappo (1st Try) : 1,330

Saiya-jin Saga: After the Battle
Kame-sennin: 139
Kame-sennin's Turtle: 0.001
Kuririn: 206
Tenshinhan: 250
Yamucha: 177
Piccolo: 329
These levels pretty much speak for themselves. They come soon after the battle with Raditsu where Bulma uses Raditsu's scouter to locate Tenshinhan, Chaozu, and Yamucha (this part was cut from the American version of DBZ)
Saiya-jin Saga: Z Fighters Vs. Saibamen and Nappa
Saibamen: 1,200
Yamucha: 1,480
Chaozu: 610
Tenshinhan: 1,830
Kuririn (pre-battle): 1,083
Kuririn (max): 1,770
Piccolo (pre-battle): 1,220
Piccolo (max): 3,500
Gohan (pre-battle): 981
Gohan's Masenko: 2,800
Notice that the pre-battle and in battle power levels are quite different. Also note that the in battle levels are the maximum levels the fighters obtain during the course of the battle (i.e. while performing a special technique) and may not reflect their constant level throughout the battle.
Saiya-jin Saga: Goku Vs. Vegeta and Nappa
Goku: 5,000
Goku Powered Up: 8,000
Goku Kaioken x1: 12,000
Goku Kaioken x2: 16,000
Goku Kaioken x3: 24,000
Goku Kaioken x4: 32,000
Nappa: 4,000
Vegeta: 18,000
Ozouru Vegeta: 180,000
Ozouru Gohan: between 9,810 and 28,000
As stated in the manga and Japanese series, Kaioken x2 and up multiplies your maximum level by that respective amount, hence 8,000 x 4 = 32,000. Also stated, Kaioken x1 gives you a "great increase in speed, and a slight increase in power." Hence, I assumed Kaioken 1x gives you 1.5 times your normal maximum level.

A saiyan's power increases 10 times in the Ozouru state, hence Vegeta's 18,000 ups to 180,000 in his ozouru form.
Furiza Saga: Gohan and Kuririn Vs. Furiza's Thugs
Gohan: 1,500
Kuririn: 1,500
Furiza's Men: < 500
At this point, Furiza's thugs have an extremely low level. This is evident because Gohan and Kuririn dispatch them in one hit apiece! 0_o
Furiza Saga: Vegeta Vs. Kui
Vegeta: 24,000
Kui: 19,000
Vegeta easily fries Kui here. Coupled with the fact that Zarbon and Dudoria state that Kui was higher than Vegeta before he left for Earth and Vegeta's current level of 24,000, I can confidently say Kui's powerlevel is close to (but over) 18,000.
Furiza Saga: Dudoria & Zarbon Vs. Namek Fighters
Zarbon: 23,000
Dudoria: 21,000
Namek Fighters: 1,000 - 3,000
Not much going on here either. Both Zarbon and Dudoria vaporize the Namekian fighters.
Furiza Saga: Vegeta Vs. Dudoria
Vegeta: 24,000
Dudoria: 21,000
Vegeta turns the lard ass into pink marshmallows. 'Nuff said. I would also like to note that I don't think Vegeta's level changes after the fight with Kui. While many like to quote the line that "A Saiya-jin gains power after every battle", I feel this only applies to battles in which the Saiya-jin takes damage, or expend a great deal of energy.
Furiza Saga: Vegeta Vs. Zarbon (1st time)
Vegeta: 24,000
Zarbon: 23,000
Zarbon Monster: 33,000
Vegeta is only marginally stronger than Zarbon in his first form, however Zarbon is quite a bit stronger than Vegeta after his transformation. He really roughs up Vegeta good.
Furiza Saga: Vegeta Vs. Zarbon (2nd time)
Vegeta: 35,000
Zarbon: 23,000
Zarbon Monster: 33,000
After spending some time in the healing tube, Vegeta's power level goes up quite a bit, as do all Sayians when they come close to death.
Furiza Saga: Vegeta, Gohan & Kuririn Vs. Ginyu Force
Kuririn: "over 10,000"
Gohan: "over 10,000"
Gohan's Masenko: "above 20,000"
Vegeta: 20,000
Vegeta: "almost 30,000"
Gerudo: 10,000
Rikum: 40,000
Well, not much to explain here either. Gerudo is fried by Vegeta, and Rikum pounds Gohan, Vegeta and Kuririn. The manga lists Vegeta as 20,000 while powering up to fight Rikum, when earlier his max level was 24,000. Either Vegeta is worn out here, or he just figures there is no way to beat Rikum. It also seems the series tried to make more sence of this this by giving him a level of "almost 30,000."
Furiza Saga: Goku Vs. Ginyu Force
Goku (Scouter): 5,000
Goku vs Jese and Burter: bursts of 60,000
Goku vs Ginyu: max power of 180,000
Jisu: 50,000
Burter: 45,000
Rikum: 40,000
Ginyu: 120,000
Not much explaining to do here. Goku kicks the Ginyu force's ass, and rightly so.
Furiza Saga: Goku in Ginyu's Body
Ginyu in Goku's Body: 23,000
Jisu: 50,000
Vegeta: 60,000
Kuririn: 16,500
Gohan: 17,000
Vegeta, again after coming close to death, sees quite a power increase and is now able to fry Jese and take on Ginyu in Goku's Body.
Furiza Saga: Nail Vs. Furiza
Nail: 42,000
Furiza (form 1): 530,000
Even though Nail is the strongest Namek fighter, he doesn't even put a scratch on Furiza.
Furiza Saga: Vegeta Vs. Furiza (1st Time)
Vegeta: 120,000
Furiza (form 1): 530,000
Furiza (form 2): 1,000,000
Now, I realize that this is a high jump for Vegeta, but its actualy makes sence. After a grasping hands with Furiza, Vegeta is sevearly winded. On the other hand, Furiza acts as if nothing happened.
Furiza Saga: Piccolo Vs. Furiza
Piccolo (merged with Nail): 800,000
Furiza (form 2): 1,000,000
Furiza (form 3): 2,500,000
Although Piccolo's level is lower than Furiza, he is an extremely intelligent and skilled fighter. Piccolo is able to read Furiza's attacks. This causes Furiza to become flustered about not being able to easily beat Piccolo like he should, forcing his transformation. Also, Furiza is only using a fraction of his full power, as he does when fighting Goku.
Furiza Saga: Vegeta Vs. Furiza (2nd Time)
Vegeta: 300,000
Furiza (form 4 - 33.33%): 4,000,000
At this point, Vegeta is a little off his rocker. He thinks that he is now a SSj . Although he may have had the potential for going SSj , he lacked a motivating factor. While Vegeta felt entitled to becoming a SSj , he did not experience any true anger as Goku did when Furiza killed Kuririn. Also, Furiza is only using a fraction of his full power, as he did when batteling Piccolo and non-SSj Goku.
Furiza Saga: Goku Vs. Furiza
Furiza (form 4 - 33.3%): 4,000,000
Furiza (form 4 - 50%): 6,000,000
Furiza (form 4 - 70%): 8,400,000
Furiza (form 4 - 100%): 12,000,000
Goku's Base Level: 300,000
Goku Kaioken x10: 3,000,000
Goku Kaioken x20: 6,000,000
SSj Goku: 15,000,000

 
Furiza's Levels as he Fights Goku:
Goku Furiza's % of Max PL
Kaioken x10 33%
Kaioken x20 33% (short time), 50%, and 70%
SSj Goku 70% and 100%


 

As you dubbies have no doubt heard "Furiza was using 1% of his power while fighting Goku." This is more evidence to prove my theory that English power levels mean crap.

I have tried many different ways to match up the different levels of Furiza and Goku's power. I hope he chart on the right helps this problem.

Please note: Goku never fighs Furiza using his base level of 300,000. Also, the manga never says anything about going SSj causing one's powerlevel to multiply by 50. In fact, it is stated durring the battle with Android 19 that math cannot be used to calculate a SSj's powerlevel.
Furiza Saga: Trunks vs King Cold and Furiza Bot
King Cold: 13,000,000
Furiza Bot: 12,500,000
Trunks (Supressed): 5
SSj Trunks: 17,000,000
SSj Goku: 20,000,000
Furiza probably experienced a slight powerlevel boost with some of the electronic parts that now make up his body.

Being his father, and being much older, King Cold is probably slightly stronger despite the fact that he appears to be in his second form. Also, Tenshinhan senses a ki "even greater than Furiza's" traveling alongside Furiza.

ALL LEVELS AFTER THIS POINT ARE A GUESS!
In the mangas, Japanese series, and Daizenshuus, Toriyama NEVER listed or authorized any power levels after the Furiza Saga, as he felt they limited his ability to be flexable and creative with the outcome of battles. If you go to another site claiming to have official levels after this point, they are mistaken. In general, these sites are using information from the "Dragonball Guide Book" which was published in 1996. Don't let the book's name fool you however, as the facts put forth in the power levels section of the book in no way corrispond to the facts stated in the series, manga, or daizenshuu.
