This blog is a work in progress, just an FYI more calculations and feats will be added as I locate more feats
Chapter 1, Tatsumi kills a large creature[]
So in the very first chapter of the series, we see Tatsumi defeat a large creature. So I will be trying to calculate what kind of AP the thing would have via tunneling through the ground.
According to this, a horse is 12 feet tall when standing on its hind legs. So I'll be using this to scale the image.

12 ft= 3.65m
3.65/162= 0.022 m/Px
751 Px = 16.92 m
637= 14.01m
So we have height, and width of the volume of Earth that this creature is able to destroy simpily by moving. This would be a cylinder.
Putting this into a volume calculator, we get 2608.35 cubic meters, this equates to 2.60835e9 Cubic Centimeters.
This feat is blatant fragmentation, so we'll be using that. But in the unlikely case the calc group thinks otherwise, I'll calc that as well.
Fragmentation: 2.08668e10 Joules, 4.98 tons. Large Building level
Violent Fragmentation: 1.7997615e11 Joules, 43.01 tons City Block level.
Chapter 2, Akame's casual speed[]
I'll be using the same method that this calculation used
In that next scene, Akame appears to move a little bit beyond those men. So I'll scale the distance she moved to the edge of the first scan just to be safe.
164 cm= 1.64m
1.64/304 px= 0.0053 m/px
Distance Akame moved, 1526 Px
This equates to 8.23 meters.
There are two ends to use. Normal Human FPS of 60 FPS. Or Peak Human FPS of 220 FPS. I'll go ahead and calc both. My reasoning for using this method is that these guys were completely unaware she even moved, only knowing once their necks were cut. So this method makes sense.
1/60= 0.016 seconds= 514.375 m/s, Supersonic
1/220= 0.0045 seconds.=1828.89 m/s, Hypersonic Eh, nothing special, but a good supporting feat
Chapter 2, Mine's Firepower When Not In Danger[]
This will be a bit tough to calculate in terms of scaling, but I'll certainly try.

Where the red line is, was a line that I figured to be a tree. I'm going to use this, because honestly it's all I've got to scale this image.
I'll assume it's an average Oak tree, that averages 50-70 Feet in height
50-70 ft = 15.24-21.33m
To be safe, I'll use the lower end of the average.
15.24/15= 1.016m/Px
Length, 183 Px= 185.92m
Depth:,26 Px = 26.41m
I suppose that using a half clyinder for this would be best.
Volume equates to 407392.27 m/3, this equates to 4.0739227e11 Cubic centimeters.
The pannel shows Mine vaporizing a dude, and steam rising from that trench. So this is pretty blatant vaporization.
25700*4.0739227e11= 1.0469981339e16 Joules, = 2.502 Megatons, Small City level
Well...... shit. I sure Hope I did this right.
Zainybrainy's version
Diameter of hole - 44 pixels
44 x 1.016 = 44.70400 / 2 = 22.35200 meter radius
(pi * 185.92 * 22.35200^2) / 2 = 145907.886 x 1,000,000 = 145907886000 cm^3
145907886000 x 25700 = 3.74983267e15 Joules, or 896.231518 Kilotons of TNT
Large Town level+
Some Zero Feats, Cornelia lifts a big rock, and some guy dodges a bullet[]
Two simplistic calculations here.

168 Cm= 1.68m
1.68/313= 0.0053m/Px
Height = 1.47m
Width= 1.49m
Length= 5.56m
Plugging this in, we get a volume of 12.17 Cubic meters.
I don't know the composition of the chunk here. But I'm going to assume Concrete.
12.17*2400kg/m^3 = 29,208 Kg, Class 50.
So begins my pitiful attempt at calculating this projectile-dodging feat. Eh, might as well try.

Assuming that guy is 1.7 meters tall. This equates to 0.0081 m/Px.
Distance bullet traveled, 3.92m
That wooden post behind the guy appears to be the same height as him, and we see it in the next pannel.
1.7/78= 0.021m/Px
Distance the guy moved,10.43 meters.
Now for the rest of the math.
The gun the girl fires looks like a handgun, so I'll be using the muzzle velocity of a 19mm Parabellum, with a muzzle velocity of 426 m/s.
The projectile would take 0.0092 Seconds.
The guy moved 10,43 meters before the bullet reached him, so this equates to a speed of 1133.7 m/s, Mach 3.33, Supersonic+
I'm really iffy on if I did this calculation correctly. So untill a calc member comes along, take this with a grain of salt.
