Well, today i'm gonna calculate this feat . Basically Arcueid raise her hand an obliterate a Town/City and a part of a mountain on the back, All of this happened 800 years ago when she was nothing more than a weapon to the extent that she even ignored the fact that she was the same kind of creature as those she was supposed to destroy.

Also, **this feat is canon**...the backstory of Arcueid was writted by Nasu for both, the anime and manga. In the manga those are the flashback from 800+ years ago.

## Calculation

First is about the pixel-scaling...i was thinking on use a random house and search for the average height of a house 800 years ago (quite common)

Anyway, so i notice that on the scan, there was a bunch of Templar Knights corpses (on the bottom left corner). so i assume that the location was around near places to the crusades...

Among all the crusades, the topography of mountains ranges from 250m to 5200m.

So i will use **250m** more than average **for a Low end** and **500m for a Mid end**, 1000m for a **High end** and **2000m** for an **Absolute High end**.

28 Px = 250m

63 Px = 562.5m

### Low End

First let's do the angsize.

**628 Px = Panel Height**

2*atan(tan(70/2)*(Object height/Panel height))

2*atan(tan(70/2)*(63/628)) = **8.03614088 degrees**

Using the angular size calculator , I got a distance of 4003.9m

63 Px = 562.5m or **a radius of 281.25m**

**Distance = 4003.9m**

Shaping it into a Cylinder (using this calculator )

V = 995,389,202.0089277 m³

**Half of 995,389,202.0089277 = 497,694,601.00446385** (Given the fact that is half of the cylinder)

497,694,601.00446385 m³ = 497694600000000 cm³

**Pulverization of Rock = 214.35 (j/cc)**

E = 497694600000000 * 214.35

E = 106680837510000000 J

Using this converter from Joules to Megatonnes

I got: **25.49733210086 Mt** or **City level**

### Mid End

For the End i will use 28 Px as 500m...So:

28 Px = 500m

63 Px = 1125m or **a radius of 532.5m**

Using the previous angsize formula: it's 8.03614088 degrees

Using the angular size calculator but with a size of 1125m instead of 562.5m from the previous end, i got a distance of 8007.8m

**Distance = 8007.8m**

Shaping it into a Cylinder...

V = 7,963,113,616.071422 m³

**Half of 7,963,113,616.071422 = 3,981,556,808.035711** (Given the fact that is half of the cylinder)

3,981,556,808.035711 m³ = 3981557000000000 cm³

**Pulverization of Rock = 214.35 (j/cc)**

E = 3981557000000000 * 214.35

E = 853446742950000000 J

Using this converter from Joules to Megatonnes

I got: **203.97866705306 Mt** or **Mountain level**

### High End

For the High End i will use 28 Px as 1000m...So:

28 Px = 1000m

63 Px = 2250m

Using the previous angsize formula: it's 8.03614088 degrees

Using the angular size calculator but with a size of 2250m instead of 1125m from the previous end, i got a distance of 16016m

**Distance = 16016m**

Shaping it into a Cylinder...

V = 63,706,499,999.99995 m³

**Half of 63,706,499,999.99995 = 31,853,249,999.999975** (Given the fact that is half of the cylinder)

31,853,249,999.999975 m³ = 31853250000000000 cm³

**Pulverization of Rock = 214.35 (j/cc)**

E = 31853250000000000 * 214.35

E = 6827744137500000000 J

Using this converter from Joules to Megatonnes

I got: **1631.8700137428 Mt** or **1.63 Gt** or **Large Mountain level**

### Absolute High End

For this End i will use 28 Px as 2000m...So:

28 Px = 2000m

68 Px = 4857.14286m

Using the previous angsize formula: it's 8.03614088 degrees

Using the angular size calculator but with a size of 4857.14286m instead of 2250m from the previous end, i got a distance of 34573m

**Distance = 34573m**

Shaping it into a Cylinder...

V = 640,860,449,733.5448 m³

**Half of 640,860,449,733.5448 = 320,430,224,866.7724** (Given the fact that is half of the cylinder)

320,430,224,866.7724 m³ = 320430200000000000 cm³

**Pulverization of Rock = 214.35 (j/cc)**

E = 320430200000000000 * 214.35

E = 68684213370000000000 J

Using this converter from Joules to Megatonnes

I got: **16415.920977533 Mt** or **16.42 Gt** or **Island level**

I lean more towards between the **High End** and the **Absolute High End**

Even more, given the fact that this feat is more than casual.

And I guess that Nasu wasn't joking when he said that 30% Arcueid is equal to 4 Servants and can fight against Gilgamesh (F/SN)-
