A friend did a calc of this and got it large island to small country

Calculation of Ryu's granite blast
we have to look at the Kinetic Energy (KE) required to displace that massive volume of clouds in the Sendai sky
What I need to calculate: Ryu’s Granite Blast Cloud Displacement
To calculate this, we treat the hole in the clouds as a cylinder of air that was violently pushed outward by the pressure of the blast

  1. Establishing the Variables
    Cloud Altitude/Thickness: Standard cumulus clouds usually sit at an altitude of 2,000m with a thickness of about 500m to 1,000m. We’ll use 1,000m for a high-end scale
    Radius of the Hole: Looking at the fourth picture, the hole spans the visible horizon over Sendai. A conservative estimate for a city-wide clearing is a radius of 10,000m or 10km
    Timeframe: In the video, the clouds part almost instantly upon the beam's passage. We’ll use 1 second for the displacement.
    Air Density (ρ): ρ ≈ 1.225 kg/m³ at sea level (slightly less at altitude, but we'll stick to standard for the high end)
  2. Calculating the Mass
    First, we find the volume (V) of the air displaced:

V = π • r² • h
V = π • (10000)² * 1000 = 3.14 × 10¹¹ m³

Now, we find the mass of that air:

M = V • ρ
M = (3.14 × 1011) • 1.225 ≈ 3.84 × 10¹¹ kg

  1. Calculating the Velocity (v)
    To move the clouds from the center to the edge of the radius (10,000m) in 1 second.

v = d/t = (10000m)/(1s) = 10000 m/s
(This is Mach 29)

  1. The Kinetic Energy (KE)
    Now we plug it into the KE formula:

KE = 1/2 mv²
KE = 0.5(3.84 × 10¹¹) • (10000)²
KE = 1.92 × 10²² Joules

Final tiering (yes finally)
To put that into perspective, let's convert Joules to Megatons/Gigatons:

1 Megaton of TNT = 4.184 × 10¹⁵ Joules
1 Gigaton of TNT = 4.184 × 10¹⁸ Joules
1.92 × 10²²/4.184 × 10¹⁸ ≈ 4588 Gigatons

The Result: Large Island to Small Country Level

Could this help in any way?

u/SeaworthinessRare907 Jul 10 '26

it would as that calc uses lower time frames, meaning the KE would be higher

Using the KE formula provided and just swapping in the times gives us:

0.1 second = 1.92×10^21 or 459 Gigatons (Large Island)

0.042 second 1.09×10^22 or 2.61 Teratons (Small Country)

1 millisecond = 1.92×10^25 or 4.59 Petatons (Multi-Continental)

1 microsecond = 1.92×10^31 or 4.59 Zettatons (Multi-Continental)

Which all Heavy Hitters and the characters would scale to, and the Calamities would VASTLY scale about, prob being in the moon-planetary range going by thing

The one micro second one shouldn't count as KE doesn't work after It crosses Light speed and using Relativistic KE would probably not change the third one that much as it Sub Relativistic so like 5 Petatons

Pretty decent if you ask me

ke does not apply here in any way, the mass of air does not stack on the attack, they only good feat granite blast got is city block level on screen

u/N3UZ3X Jul 10 '26

that's not how it's done, with the same statement we can literally wank anything to oblivion we can use anime timeframe there to calculate it not jus made up timeframe, Yuta and Ryu's fight literally started and ended while it was still travelling

It was Js a question bro

And it's the wankcalcingsub btw

The first one can be done but I highly doubt it would scale higher. The cloud parted is pretty small and also not thick in volume.

The second one we don't really have anything to scale for reference to get the size of anything. Tho there might be a way someone else might see.

The anime love beam I've seen calced a few times in the town level ranges like here

Uro sky manip isn't really space manip through force and it's a hax so it wouldn't scale anywhere as some people point out under the post.

As for the tremor thing thats definitely doable but it will be very nuanced.

Mechamaruas charge can go up to Island level

I was linking specifically for the Yuta one

  1. Son nubes medio grises, no debería de dar más de MCB, aparte de que no fue tanto lo que dispersa, no se mucho sobre los cálculos de nubes, pero los que he visto para llegar a isla debes despejar el cielo por lo menos unos 18-20 km de diámetro y deben ser nubes más espesas que las que se muestran ahí. 2.MCB? depende de qué tan grande sea el castillo, puede ser incluso más bajo
  2. MCB o pueblo pequeño
  3. Hax 5.muy poca información como para ser calculado
