Summary[]
This is a compilation of calcs for feats from the newly released 2025 Superman movie in theaters now
Calculation 1 - Kaiju GPE[]
The movie provides us with both the exact height and weight of the Kaiju courtesy of Mr. Terrific so lets calculate the Kaiju's GPE
319 ft or 97.45m (Large Size Type 1) very close to type 2
18397576 lbs = 8345000.1kg or 8345.0001 Metric Tons (Class M)
The center of gravity is about half your height so 48.725m is what we're working with
8345000.1*9.81m/s^2*48.725m = 3.98884537e9 Joules or 0.953357 Tons of TNT (Building level)
Calculation 2 - Kaiju fire breath[]
a Kaiju breathes fire bathing superman and the building behind him in flames, feat happens here.
The 2024 average global temperature is 17.16°C
Orange flames range from around 1100°C to 1200°C so we'll use 1150°C as our median.
David Corenswet height: 6′ 4″ or 1.93m
1.93m/45.55 * 133.97 = 5.67644566m
1.93m/45.55 * 1705.68 = 72.2714029m
Cylinder volume: 1828.98m^3
Density of Air = 1.216 kg/m3
1.216 kg/m3 * 1828.98m^3 = 2224.03968kg
Specific Heat = 1.006 kJ/(kg*K)
2224.03968kg * 1006 J/(kg*K) * (1150 - 17.16) = 2534597998 Joules or 0.60578 Tons of TNT (Building level)
Calculation 3 - Superman Crashes in Antarctica[]
Superman travels from Antarctica to Metropolis (which is located in Deleware) in 3 minutes crashing into the ground at full speed
The distance from Denver to Antarctica is roughly 12400km
12400km/180s = 68888.8889m/s or Mach 200.84224 (Massively Hypersonic)
David Corensweat is 230 pounds or 104.326kg
0.5 * 104.326 * 68888.8889^2 = 247548854401 Joules or 59.165596 Tons of TNT (City Block level+)
Now Superman does fly back on his own to fight the Hammer of Boravia again as he stays monologuing in the city without any drastic change in timeframe so we'll do two ends for his return flight speed
5 minutes[]
12400km/300s = 41333.3333m/s or Mach 120.505345 (Massively Hypersonic)
10 minutes[]
12400km/600s = 20666.6666999999361m/s or Mach 60.252673 (High Hypersonic+)
Calculation 4 - Superman Smashes a water tower[]
Feat happens here (Updated footage here)
1.93m/40 * 150.57 = 7.2650025m (ellipsoid diameter)
1.93m/40 * 104 = 5.01800m (Half ellipsoid height)
Half Ellipsoid volume: 138.675m^3
1.93m/40 * 160.25 = 7.7320625m
1.93m/40 * 129.10 = 6.229075m
Cylinder volume: 292.49m^3
total volume: 431.165m^3
We'll go with 99% hollowness since its water tower
431.165 * (1-0.99) = 4.31165m^3
431.165 - 4.31165 = 426.85335
AP[]
4.31165m^3 * 208 J/cc = 896823199.99858403 joules or 0.2143 Tons of TNT (Small Building level+)
LS[]
4.31165m^3 * 7850 kg/m^3 (Steel Density) = 33846.4525kg
426.85335m^3 * 1000 kg/m^3 (Water density) = 426853.35kg
Water tower weight: 33846.4525kg + 426853.35kg = 460699.802kg or 460.699802 Metric Tons (Class K)
1.93m/40 * 19.11 = 0.9220575m (Arm length)
1.93m/40 * 172.37 = 8.3168525m (water tower leg length)
0.9220575m + 8.3168525m = 9.23891m, Superman swings the water tower from behind his back about 180 degrees so our arc length is 29.0249m
11.55s - 10.70s = 0.85s (timeframe it takes for Superman to swing from behind the back to having his arm fully extended forward)
29.0249m/0.85s = 34.1469412m/s
460699.802kg * 34.1469412m/s^2 = 1604165.4388kg or 1604.1654388 Metric Tons (Class M)
Calculation 5 - Superman Divebombs from Orbit[]
Feat happens here (Updated footage here)
Space starts at 100km
39.60s - 9s = 30.6s
100km/30.6s = 3267.97386m/s or Mach 9.52762 (Hypersonic+)
David Corensweat is 230 pounds or 104.326kg
0.5 * 104.326 * 3267.97386^2 = 557082747.245 Joules or 0.13315 Tons of TNT (Small Building level+)
Calculation 6 - Superman Flies to Space[]
Feat happens here (Updated footage here)
Space starts at 100km
Superman takes off at 3.60 and is shown in space by 67.20 so he spends 63.6s flying
100km/63.6s = 1572.32704m/s or Mach 4.584 (Supersonic+)
