Overview
The 'Blast Radius' or Scaled Distance is a standard way to estimate the damage from an explosion. It relates the radius of the blast to the cube root of the mass of the explosive.
💡
Pro Tips
Different 'Z' values correspond to different levels of damage (e.g., 0.5-2 for major structural damage).
Weight is usually in kilograms (TNT equivalent) and radius in meters.
The cube-root scaling law is common in blast engineering.

Fun Facts
"TNT (Trinitrotoluene) is the standard reference for explosive energy."
"Nuclear weapon effects also follow scaling laws, but they involve additional factors like thermal radiation."
"A car's airbag deployment is a controlled explosion that happens within milliseconds."
