I've been hoping to find a way to quantify this for years, but wasn't sure how to. But no more! MEDUSA destroys the city of Panzerstadt-Bayreuth, and later self-destructs, taking London with it. When Tom and Hester are captured by Speedwell, Shrike is noted to be hundreds of miles away (by...

Larklight's gravity engine explosion creates a crater 1000 miles (1609.344km) wide and at least as deep as Starcross is. We don't have many references to how big Starcross is that I can recall, but it's well over 100 yards (91.44m) wide. Volume of the crater as a spherical cap. V = (π X...

The Uncrushable flies from Io to Jupiter in a few hours. The distance from Io to Jupiter is 628,300,000km. We'll go with a high end of 3 hours, a low end of 10 hours and a mid end of 6 hours.. (Low end) T = 628,300,000km/10h = 29087963/340.29 = Mach 51287.9538 (Mid end) T =...

Jupiter is mostly hydrogen, so they'd likely weigh as much as hydrogen. Radius of the Moon is 1737km. V = 4/3πr^3 = 4/3 X π X 1737^3 = 2.19527062e10km^3 = 2.19527062e+19m^3 Hydrogen weighs 0.0899^2kg per m^3. M = 2.19527062e+19 X 0.0899^2 = 1.77421991e17kg The heat of...

Larklight flies 30,000 miles (48280.32km) in the span of a few seconds. We'll have a low end of 10 seconds, and a high end of 3 seconds. (Low end) T = 48280.32km/10s = 4828032/340.29 = Mach 14187.9926 (High end) T = 48280.32km/3s = 16093440/340.29 = Mach 47293.3086 Final Results...

Mortal Engines is a world where cities wander around and eat each other for reference. First up is an easy one; Salthooks speed. 80m/h is equal to 128.7km/h, or 35.75m/s. And London is even faster than this. Now onto it's energy. The speed is 80 miles an hour (35.7632m/s), and has a height of...

Because I feel like it time for some more calcs, in this case for the total environmental effects of the 60 Minute War on the Earths surface. There's a ton of descriptions of earthquakes, volcanos, firestorms and centuries of darkness, but for the most part, it can't really be calced so far...or...

50 megatons. Absolutely painstaking. :nonon Final Results The Scrivener Institute's durability = 50 megatons

After the 60 Minute War, multiple Slow Bombs hit the Earth, one of which destroys Panama, seperating North and South America. A quick search reveals that Panama has a surface area of 75,517 km^2, or 75517000000m^2. It also has an average elevation of 360m. V = Ah = 75517000000 X 360 =...
