Petanewton (Extreme Scientific Force Unit)

Introduction : One petanewton is 10^15 newtons—a unit used in hypothetical physics models to describe massive interactions such as gravitational forces between large celestial bodies.

History & Origin : Though practically unused in engineering, the petanewton emerged from SI’s prefix system for completeness. It remains a theoretical value in astrophysical computations.

Current Use : Used in simulations of gravitational forces between stars or during events like supernovae. It is not applied in real-world technology due to the extraordinary magnitude.

Sthène (MTS Unit of Force)

Introduction : The sthène is a large unit of force defined as 1,000 newtons. It was introduced in the metre-tonne-second (MTS) system of units and is rarely used today but remains historically important as a precursor to modern SI conventions.

History & Origin : The sthène was used in the MTS system, developed in the early 20th century in France. Although the system never saw global adoption, the sthène offered a clean metric-based force unit, especially suitable for large-scale industrial forces.

Current Use : While largely obsolete, the sthène appears in historical scientific literature and industrial documentation from the MTS era. Occasionally referenced for academic comparisons or unit conversions, its magnitude (1 kN) aligns closely with real-world structural force values.
