If you're asking how kili translates to traditional scouter numbers, it's 1 kiri = 50K PL/BP according to the V-Jump 2004 magazine:

If you did not consider Dabura's statement about the amount of kiri required to destroy a planet or two and just waived it off as something trivial, then you're up for a shocking wake up call

the power level (PL) required to destroy an "average" planet or two in Dragon Ball is about 200-300 kili or kiri as it's called in japanese. The term "kili" (or "kiri" in Japanese, since there's no "L" sound in the language) is a pun on riki, the Japanese word for "power." It essentially equates to "power level."

This makes sense when factoring in Dragon Ball's physics-defying logic, where many planets appear far larger and more durable than Earth.

Even in our universe, we've got examples like super-Earths, which are significantly larger than Earth. While mega-Earths are sometimes classified differently due to their habitability, the line between them can get blurry. Since this is Dragon Ball, where planets can have 10x Earth's gravity without collapsing, the standard rules of physics clearly don't apply.

Here's a breakdown of some notable super-Earths:

Terrestrial planets (rocky planets like Earth) generally max out around 10x Earth's mass, although exceptions like Kepler-10c exist. Anything beyond this usually transitions into mini-Neptunes or gas giants.

If we take Kepler-10c's mass as the extreme highball, requiring , then destroying such a planet would demand 17 times more PL. Considering that Vegeta was blasting Earth with more than , this tracks.

Thus, Dabura's implication that you'd need about . Comparing the size and durability of Dragon Ball planets to real-world examples, this aligns with Dragon Ball's DC/AP power scaling. It's worth noting that in the Dragon Ball cosmology, , which contradicts real life, where Earth's classified as an average sized rocky planet.

This means not only that the larger terrestrial planets in Dragon Ball must be significantly bigger and more massive than in real life, but also that some would require more than a single shot from Cold -- a huge game-changing detail that can be elusive and hard to grasp when encountered for the first time that a lot of people just gloss over it. Keep in mind that Cold is somewhat weaker than Freeza, contrary to what many people headcanon, such as him having different transformations or being comparable to Freeza in strength.

TL: Though he's the head of the strongest family in the universe, he is somewhat inferior to Freeza.

Although, the fact how someone with would still need more than a single shot to destroy the average or large planets of DB is still bonkers

Now, how much bigger than Earth would this "average-sized" Dragon Ball planet be in comparison to our real-world Earth? Let's see!

For example, the gravitational binding energy (GBE) required to destroy Kepler-10c would be approximately 50-55 times that needed for Earth. In simpler terms, you'd need over 50 times the energy to blow up Kepler-10c compared to Earth. Since Vegeta's Galick Gun was matching Goku's Kaio-ken x3 Kamehameha -- putting it at a minimum of 25,800 in terms of PL output given Goku's 8,600 PL at the time -- this scales logically. as multiplying 25,800 by 50-55 gives us a range of 1,290,000 to 1,419,000 PL which is still 3,5x-3,9x times shorter than the 5M PL requirement. If Earth is a "small" planet, then Dragon Ball's average-sized planets must be this much larger than Kepler-10c if it's around 5,000,000 (100 kiri) to 10,000,000 PL (200 kiri), which aligns with the established conventions.

The "average" planet in Dragon Ball, based on the calculations for a required power level (PL) of 5,000,000 to destroy it, would have approximately 216-343 times Earth's mass and 6-7 times Earth's radius, making its GBE 200-400 times Earth's GBE. In terms of size, Earth would be significantly smaller in both mass and radius compared to this planet. To break it down: since volume scales with the cube of the radius, this Dragon Ball planet's volume would be approximately 216-343 times Earth's volume.

to reiterate, it'd be in terms of mass-wise, it's 216-343 times Earth's mass, meaning it's also much denser than Earth (but that doesn't get accounted for in fiction because Toriyama isn't a physicist, nor does fiction have to abide by real-world physics). As for GBE, which represents the energy needed to completely overcome a planet's gravity and disperse it, this Dragon Ball planet's GBE is 200-400 times Earth's GBE, meaning it would take 200-400 times the energy/PL required to destroy Earth and obliterate it. To put this into perspective, Kepler-10c, a massive real-world super-Earth that is 17 times Earth's mass and 2 times Earth's radius, has a GBE roughly 50-55 times (or more) of Earth's GBE. This Dragon Ball planet surpasses even Kepler-10c, requiring nearly 4-8 times Kepler's GBE to destroy it.

Therefore, Earth is roughly 216-343 times smaller in volume and mass, making it truly diminutive and small compared to what Dabura (and by extension, cold) considers "average" in Dragon Ball, where planets routinely break the rules of physics and exist as absurdly massive yet mystically reinforced and created celestial bodies. Earth being a "small planet" in King Cold's view really makes sense, given that even an "average" Dragon Ball planet would be 6-7 times Earth's size and require energies far beyond what real-world science would allow or accept in RL for destruction.

Dabura claims that destroying an average-sized Dragon Ball planet requires 200 kili (with 100 kili as the absolute minimum). Since Dabura also states that 200-300 kili can destroy one or two planets, scaling up from 200 to 300 kili doubles the energy's effect, meaning 100 kili is the absolute minimum. When we compare this with Vegeta's Galick Gun, which destroyed Earth with a 25,000 PL, 200 kili (equivalent to 10,000,000 PL) is 400 times stronger than Vegeta's Galick Gun. For the absolute minimum of 100 kili (equivalent to 5,000,000 PL), the ratio becomes 200 times Vegeta's 25,000 PL.

Dabura's claim implies that destroying an average-sized Dragon Ball planet would require 5 to 10 million PL, corresponding to 100-200 kili or 200-400 times the strength of Vegeta's Galick Gun. This comparison highlights the immense scale of destruction possible in Dragon Ball, where even "average-sized" planets demand energy levels that far exceed RL typical destructive limits for terrestrial earth-like

Caveats:

As many of you might know, Dragon Ball is a fictional universe. Akira Toriyama was ; he simply created the story as he saw fit, without overthinking the scientific plausibility. For example, Planet Vegeta, with 10 times Earth's gravity, would be impossible to translate into real-world physics or math. A planet with that gravity would have a GBE 100,000 times that of Earth, requiring an absolutely monstrous energy level to destroy. However, we know this isn't the case because Frieza, at only , destroyed it effortlessly. Not only that, but Dragon Ball is like Star Wars in terms of science fidelity, in the sense that gravity doesn't seem to have much to do with planet size. It's plot-driven or thematic in nature. For example, King Kai's planet, which was smol planetoid the size of a 100 meter one in diameter still had 10x Earth's gravity. The Super Dragon Balls have a radius four times that of Earth, and they seem to have about the same gravity. Namek has three suns, and despite orbiting between them, it still has hospitable temperatures, a habitable climate, and the same gravity as Earth. Thus, Planet Vegeta having 10x Earth's gravity hardly tells us anything about its size, only its gravity. That's it. Therefore, it's crucial to remember that planets in Dragon Ball don't translate well to real-world physics and science hence why treating their RL defying physics

in other words, don't be like those kind of people who say stuff like this: https://web.archive.org/web/20160304030504/http://www.screwattack.com/news/gokus-punchingkickingstriking-power

Not only does this person assume that King Kai's planet's gravity is due to literal physical properties rather than some kind of afterlife thaumaturgy employed by King Kai on his planetoid, as evidenced by the fact that his 1957 Chevrolet Bel Air hardtop doesn't get crushed under the 10x times Earth's gravity and beerus already destroying most of its which made it smaller than the other kaio's planets

all of this is visually and textually self-evident but such people more often than not choose to ignore this and conveniently sweep it under the rug. On top of that, their calculations are super incorrect, making it all the more ironic that such claims often come from individuals who are math-illiterate who rely on pseudo-mathematical bumbo jumbo to back up their arguments. XD. here's the proper physics/math to debunk these fabrications.

The claim that King Kai's planet is more durable than the Sun or a white dwarf star doesn't stand up to scrutiny when we examine the numbers. If we assume King Kai's planet has gravity 10x that of Earth and is about 100 meters in radius, its density would need to be approximately 55.1 g/cm³, or 55.1 million kg/m³. For comparison, the Sun's average density is 1.41 g/cm³, equivalent to 1.41 million kg/m³, but this is misleading because the Sun's core density -- where nuclear fusion occurs -- is a staggering 150 g/cm³ (150 million kg/m³), far surpassing King Kai's planet's assumed density. Now consider a white dwarf star: its density is an unimaginable1 billion kg/m³, which is 1,000 million kg/m³, or 1,000 times denser than even the Sun's core, follow up below:

''King Kai's planet must be incredibly dense to generate 10x Earth's gravity, especially given its small size. For gravity at that magnitude, the planet's mass would need to be highly compressed and Distance matters when calculating gravitational pull, so such a dense composition is the only explanation which means it must be denser than the the sun's core'' - boneheads

This was mathematically and narratively debunked above, but if you want more of me clamping down on these pseudoscientific circle-boneheads and their entire existence, then read on as I smack them down in a single rant of scientific rage and fury to crush these pseudo-intellectuals' asses. So strap in, because we're diving headfirst into this black hole of stupidity and pseudoscience. tho if you've had enough, feel free to skip the spoilers block!

side tangent:

all these stuff is why things gotta be approached from their in-universe empirical perspective, considering the statements and what the characters know of such things, for a full and thorough understanding and not a wanked one based on a faulty methodology of applying RL physics to mystical shows as if they're RL
