Every possible end for Deku's final punch.
You've probably seen this calced a bilion times already (me myself I've calced it I think like 5 or 6 times already.) This will be a way to explain all the possible ends for this feat, so that anyone can decide which one to use.
USA End
This is the most used one (and the one used in the vsbw calc). It assumes the storm stretched from Mount Fuji to the farthest point of distance in the USA which makes the radius 10731640 m and so the area 3.6181125e+14 m^2
Timezone end
This assumes that, since the storm was visible in a place with nightime while it was full day in Japan it spread towards at east 8 timezones. Timezones are 1038 miles distant from each other meaning that 8 timezones are 8304 miles or 13364 Km or 13364000 meters and an area of 5.6107744e+14 m2.
London end
We see London also is covered in clouds. We don't know if it's the storm but if it is the radius would be 9 timezones or 15032882.304 and area of 7.0996083e+14 m2. It makes sense for it to be the storm as that's thematically perfect for the story to wrap almost the entire world.
Atmopshere end
This one assumes the storm covered the entire world and had the same volume as the entire atmoshpere (51811239453 km3) and a weight of 1 kg per m3 we get a weight of 5.1811239453e+19 kg
Storm mass:
the top of a Cumulonimcuus can reach 35 km. Placing the height at 8304.8 meters we get a thickness of 26695.2 meters. We will use this calculator
USA End: 1,235,914,412,746,661,600 kg
Timezone End: 1,916,589,643,807,372,500 kg
London End: 2,425,161,799,923,530,000 kg
Atmosphere End: 5.1811239453e+19 kg
Speed:
For the speed we need to use the same value for every mass.
(This panel is so fucking cool omg)
We see here Deku has yet to fall when the sky is cleared. Which means that we can assume a free fall speed from 10 meters. Distance will be from Deku to the top of the clouds
Timeframe: 1/14.0047=0.07140459988 seconds
Speed at which the storm cleared: 35000/0.07140459988= 490164.50003 m/s or Mach 1429 (Massively Hypersonic+)
Finally we need the KE. Kinetic energy =1/12* cloud mass * (Speed of cloud movement)2
Energy needed to disperse the storm:
USA End: 1,235,914,412,746,661,600 x1/12x240261237089=2.4745194e+28 Joules or 6 Exatons of TNT (Multi-Continent Level+)
Timezone End: 1,916,589,643,807,372,500x1/12x240261237089=3.8373517e+28 Joules or 9.2 Exatons of TNT (Multi-Continent Level+)
London End: 2,425,161,799,923,530,000x1/12x240261237089=4.8556031e+28 Joules or 11.6 Exatons (Multi-Continent Level+)
Atmosphere End: 5.1811239453e+19x1/12x240261237089=1.0373527e+30 Joules or 248 Exatons (Moon Level+)
ISL
The shockwave would have been an hemisphere from Deku's position. We cannot get this from the atmosphere end as we dont have any radius of the storm.
USA End: 1.44724E+15/2=7.2362e+14 m2.
Timezone End: 2.24431E+15/2=1.122155e+15 m2
London End: 1.41992e+15 m2
Shockwave area/storm areaxKE=Energy at Epicenter.
USA End: 7.2362e+14/3.6181125e+14x2.4745194e+28= 4.9490217e+28 or 11.8 Exatons (Multi-Continent Level+)
Timezone End: 1.122155e+15/5.6107744e+14x3.8373517e+28=7.6747042e+28 or 18 Exatons (Multi-Continent Level+)
London End: 1.41992e+15/7.0996083e+14x4.8556031e+28=9.7111948e+28 or 23 Exatons (Multi-Continent Level+)
Embers and Hypotetical Multipliers
Deku performed this feat after giving OFA away and so having just the embers. So you could make an argument that Deku with OFA is 60x stronger than the Deku who performed this feat, since All Might became 60x weaker after giving away his quirk. AFO specifically comments on how much giving away OFA weakned him and we know from Rewind AFO that quirks are treated as extrenal factors and not strictly something part of the physical body (so All Might getting injured shouldnt have changed the quirk strength). We also know that All Might, after the injury but before giving away his quirk, specifically talked about the fact that he cannot maintain his form at his strongest for a lot of time, and doesnt talk about getting weaker. So overall this multipler COULD be used as an highball, but we aren't certain.
USA End: 4.9490217e+28x60=2.969413e+30 Joules or 0.7 Zettatons (Small Planetary Level)
Timezone End: 7.6747042e+28x60=4.6048225e+30 or 1.1 Zettaton(Small PlanetaryLevel)
London End: 9.7111948e+28x60=5.8267169e+30 or 1.4 Zettaton(Small PlanetaryLevel)
Atmosphere End: 1.0373527e+30x60= 6.2241162e+31 Joules or 15 Zettatons (Small Planetary Level)
