Sukuna’s Fuga
Feats: Sukuna uses Fuga in Shinjuku against the Heavy Hitters
Shinjuku Building Height = 100m or 83px 1px = 1.20481927711m
Fire Blast Height = 2003.61445783m
The Blast covers the Domain radius which is 200m
Volume = 83927206151267.0156 cm3
Assuming 75% Hollowness
True Volume = 6.2945405e13 cm3
Based on the damage, I’ll be assuming 50% Pulverization and 50% Vaporization
Destruction Value = 12957 J/cm3
Energy = 8.1558361e17 Joules
However we also know that Fuga pulverizes substances to gain Explosive Cursed Energy
In other words, Thermobaric Explosives
So we can use that to calculate this
A common type of fuel used in thermobaric explosives is propane, which when completely combusted, is capable of producing over 50 megajoules/KG or 50 million joules/KG
The formula used for said explosion is: Energy = Mass x Joules
Mass = 8.1388409e13 kg Joules = 50,000,000
8.1388409e13 x 50,000,000 = 4.0694e21 Joules
Final Results
Standard End: 194 Megatons (Mountain Level) Thermobaric End: 972 Gigatons (Large Island Level)
This is not my calc
