Introduction[]
I believe I have found the best way to get this thing. So Demon Licht’s able to destroy the Clover Kingdom. I’mma calc this with Noelle’s statement that it would take Asta days to run from the base to Hage. He was going to start from the Black Bulls hideout and run straight there, according to what Noelle said + the flashback as Asta’s riding with her. Since we can’t use an assumed speed, I’ll use the speed he’s running at at that very moment.
Why This Over the Current Clover Kingdom Feat?[]
Simple: The 300 km distance is an assumption. When it was said, the people there were at some random distance from the capital, and we don’t know where specifically they were. We just took the furthest point from the capital and assumed that, even though they were definitely not at the border area. We can't even calculate how far they were, believe me, I tried. Also, it's worth noting that this happened in episode 131, which - while anime only - is canon.
Calculation[]
Asta Height = 1.55 meters = 508 px
1.55 / 508 = 0.0031 meters per px
Asta Head Width = 75 px = 0.23 meters
Asta Head Height = 0.23 meters = 25 px
Panel Height = 768 px
Distance from Asta to PoV = (0.23 * 768) / [25 * 2tan(70/2 deg)] = 5.05 meters
Asta took about a second to get this distance, so 1 second is the timeframe.
Asta’s Speed = 5.05 / 1 = 5.05 m/s (this is just his running speed in this very moment)
It was stated he’d take days to get there, so I’ll use 2 days as a low-end. Speaking of which, humans sleep for 8 hours per day, so 48 hours minus 8 hours per day, giving us 32 hours, or 115200 seconds. You could say “Asta is a trooper so he could sleep for less” but it’s because of him being a trooper that he would sleep the normal time so he can keep on trooping.
Distance from Hideout to Hage = 5.05 * 115200 = 581760 meters
Distance from Hideout to Hage = 581760 meters = 350.05 px
581760 / 350.05 = 1661.93 meters per px
Distance from Hage to Capital = 733 px = 1218194.69 meters
Distance from Hage to Capital = 1218194.69 meters = 331 px
1218194.69 / 331 = 3680.35 meters per px
Clover Kingdom Diameter = 590 px = 2171406.5 meters
Clover Kingdom Radius = 2171406.5 / 2 = 1085703.25 meters
Ground level explosion formula is W = R^3*((27136*P + 8649)^(1/2)/13568 - 93/13568)^2 where W is the yield in tons, R is the radius in meters, and P is the standard overpressure of 1.37895 bars.
W = 1085703.25^3*((27136*1.37895 + 8649)^(1/2)/13568 - 93/13568)^2
Final Result[]
Clover Kingdom Go Boom = 102.85 teratons; Large Country level (High 6-B)
FINALLY! NO CRAZY ASSUMPTION OR SIZE SHENANIGANS JUST PURE BOOM!
