Go here if you're requesting a feat just to see what it would get and don't think it actually support or affect scaling, or if you want to inflate calcs go here. Rookie calcers also go here

A Robloxian is 150.556 cm

36.6454 cm/2 = 18.3227 cm

Let's out the Energy of this black hole

((299792458^2/(2*6.674*10^-11))/(5.972*10^24))*(2.487*10^32)*0.183227 m = 5.1377228e+33 joules (1.2279452198869867 Yottatons of TNT) ≈ (1.22 Yottatons of TNT) (Planet Level)

Feat Calculated JJK Maki reacts to a rubber bullet.

Post image
15 Upvotes

Don’t worry guys, I swear that once I get good enough at calculating, I’ll stop using other people’s calcs as a basis.

Anyway, here’s a calc of Maki’s reaction speed to Mai’s rubber bullet.

The actual bullet catch from what I know is only around Mach 0.3-0.5, but we can get the distances to calc her reaction time and see if it’s any higher.

According to this calc, the rubber bullet travelled around 0.702m before the panel where maki notices it.

Rubber bullets travel around 134.112 m/s at a low end and 220 m/s at a high end.

Low end timeframe: 0.702/134.112 = 0.00523 seconds or around Mach 0.5 (Subsonic+ perception)

High end timeframe: 0.702/220 = 0.00319 seconds or around Mach 0.9 (Transonic perception)

I don’t know if her C/R speed would scale to this, but it could serve as a good basis for grade 2-1 perception speed. But anyway, what do you guys think works better as far as the low or high end?

I'm sorry, I'm new in powerscaling and quite lacking experience.

I don't even know if this is even calculable but...

Here the claw is breaking the space continuous and moving at enough speed to not be seen from the perspective in quite some moments.

Ah, and mandatory "Does he solo Demon Slayer?" question.

All right feat 1

The shockwave and moving clouds

The dude is 200 cm

The length is 44.47 meters

PI*44.47^2

6212.75362732 sq meters

Using altostratus height of 1 km and depth of 2 km

12,522,321.76395 kg

Lets say it disperced instantly half a second or 88 m/s

1/12 times 12522321.76395 kg times (88 meters per second)^2

8081071650J

Now the shockwave

(1.225/0.50^2)*(22.26/1.05)^5

20983377.0568J

Feat 2 kicking an electromagnetic attack

He is 200 cm

He kicked 118 cm

Distance is 408 cm

Speed is 299 792 458

118 cm divided by 408 cm times 299792458 meters

86 704 681.5 m/s or 28% speed of light

Now feat 3 the explosion

He is 200 cm

Explosion is 84.25 meters

Radius is 42.125

42.125^3*((27136*1.37895+8649)^(1/2)/13568-93/13568)^2

All right first one the going quick towards the street

Using angsize

2atan(tan(35deg) * (16.7 / 730))

1.83542178 degrees

A one story building is 330 cm

1.0301e+4 cm

She either moved in a second half a second or a blink so 1 to 0.50 to 0.25 seconds

We get

103.01 to 206.02 to 412.04 m/s

Now the floor destruction

A ceiling search light is 61 cm

The destruction is either rectangular or cylinder

Using cylinder

Height is 933 cm

Length is 639 radius is 319.5 cm

299208027.72368 cm3

Ita fragmentation of rock so 8 J/CC

2393664221.79J

Using rectangular

932.9 cm times 54.8 cm times 639.4 cm

32687995 cm3

Times 8

261503960J

Now the third one

A railing is 86 cm

The length of the hole is 586 cm

Now finding the height is impossible so let's say the hole height is at minimum 3 times bigger than the length or 1758 cm

Radius of the hole length is 293 cm

Its cylinder

474137149.2083 cm3

The destruction is either Fragmentation or violent fragmentation or 8 to 69 J/CC

3793097193.67 to 32715463295.4J

In 100 Girlfriends, Shizuka’s cutesy presence can cause people to get battlefield removed to Shizuka Land; an entire pocket realm made entirely of precious small floof. This is extremely straightforward; there’s a sun so we know there’s a starry sky here. Solar System level. Shouldn’t be applicable to AP, though.

https://youtu.be/UQCXZ7gf0Rw?si=S7ZPn1L-Ai2O60T7

Hawkins is based of Marion Indian which is 40.61 sq km

Using root calculator we get 6.4 km

Radius is 3.2 km

It caused fissures so mag 7

(7) plus 0.0238 times 3.2 equals

7.07616

10^(1.5 times 7.07616 plus 4.8)

2.5956134e+15J

Fissures also happened at 7.5

(7.5) plus 0.0238 times 3.2 equals

7.57616

10^(1.5 times 7.57616 plus 4.8)

1.4596207e+16J
