Convert Petapascals to Terapascals

Convert Petapascals (PPa) to Terapascals (TPa) instantly and accurately.

Conversion Formula

TPa = PPa × 1000

About Petapascals

A petapascal (PPa) = 10¹⁵ Pa - pressures found in stellar interiors. The Sun's centre is ~25 PPa, sustained by radiation pressure from nuclear fusion balanced against gravity. White dwarf stars: ~10⁴ PPa (electron degeneracy). Neutron stars: ~10⁹-10¹⁰ PPa, where nuclear structure fails and neutrons drip from nuclei at ~4 × 10⁸ PPa (the neutron drip line). The hadron-quark phase transition in the densest neutron star cores is estimated at 10¹⁰-10¹² PPa. No laboratory experiment can approach petapascal pressures. 1 PPa = 10¹⁵ Pa.

About Terapascals

A terapascal (TPa) = 10¹² Pa = 10 Mbar - pressures in giant planet cores and at the frontier of high-energy-density physics. Jupiter's centre: ~40-70 TPa; Saturn's: ~10 TPa. Earth's inner core: ~0.35 TPa; core-mantle boundary: ~0.14 TPa. Laser-driven ramp and shock compression at NIF approaches TPa regimes for fusion implosion capsule research. Hydrogen is predicted to become a superconducting metal at ~0.5-5 TPa. Understanding TPa equations of state is critical for modelling exoplanet interiors. 1 TPa = 10¹² Pa.
