        "content": "Between Semtex and TNT, **Semtex** is more powerful *per kilogram*, though the difference isn\u2019t huge. Here's a breakdown based on comparative data:\n\n---\n\n### Key Metrics of Explosive Power\n\nPower of an explosive is typically measured by:\n\n- **TNT equivalence** \u2014 how much TNT would be needed to match the same energy or effect.  \n- **Relative Effectiveness (RE) factor** \u2014 a number that shows how much more (or less) powerful something is compared to TNT.\n\n---\n\n### Semtex vs TNT: How They Compare\n\n| Explosive | Approximate Specific Energy (kJ/kg) | TNT Equivalent / RE Factor |\n|-----------|----------------------------------------|-----------------------------|\n| TNT | ~ 4,520 kJ/kg | **1.00** \u2014 baseline ([onlinelibrary.wiley.com](https://onlinelibrary.wiley.com/doi/10.1155/2018/3157457?utm_source=openai)) |\n| Semtex | ~ 5,650\u20135,660 kJ/kg | **~1.25** \u2014 meaning Semtex releases about 25% more energy per kilogram than TNT ([onlinelibrary.wiley.com](https://onlinelibrary.wiley.com/doi/10.1155/2018/3157457?utm_source=openai)) |\n\n- Semtex\u2019s higher energy density means that 1 kilogram of Semtex delivers a blast effect comparable to about **1.25 kilograms of TNT**. ([onlinelibrary.wiley.com](https://onlinelibrary.wiley.com/doi/10.1155/2018/3157457?utm_source=openai))  \n- TNT is still widely used as the reference standard because it was historically standardized, easier to handle, and has a well-understood behavior. ([totalshield.com](https://totalshield.com/blog/how-tnt-equivalent-is-applied-in-blast-containment/?utm_source=openai))\n\n---\n\n### Other Important Factors\n\nPower isn\u2019t the only thing that matters. The **effectiveness** of an explosive depends also on:\n\n- **Detonation velocity**: how fast the reaction front moves. Higher means more destructive shock. Some Semtex variants (Semtex 1A, 1H, etc.) have high velocities. ([sciencedirect.com](https://www.sciencedirect.com/science/article/pii/S221491471930220X?utm_source=openai))  \n- **Bristle / shattering effect**: ability to break or shatter materials, which depends on pressure peak, shock front sharpness, etc. Usually higher in high-energy explosives like Semtex vs TNT.  \n- **Formulation / composition**: Many Semtex versions include PETN, RDX, plasticizers, etc., altering its characteristics. ([sciencedirect.com](https://www.sciencedirect.com/science/article/pii/S221491471930220X?utm_source=openai))  \n- **Density**: Denser explosives usually pack more explosive molecules per volume, increasing effectiveness. Semtex is pretty dense. ([sciencedirect.com](https://www.sciencedirect.com/science/article/pii/S221491471930220X?utm_source=openai))  \n\n---\n\n### Conclusion\n\n- If you compare equal weights, **Semtex** is more powerful than TNT by roughly **20\u201335%** depending on the specific type of Semtex.  \n- If you have a given task (breaching, demolition, etc.), Semtex will achieve similar effects with less material than TNT.  \n\nIf you want to compare specific variants (Semtex 1A vs 1H vs a particular grade of TNT), I can pull up more detailed numbers."
