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.
About Kilopounds per Square Inch
One ksi (kilopound per square inch) = 1,000 psi ≈ 6.895 MPa - the standard engineering stress unit in the US. ASTM A36 structural steel: 36 ksi yield, 58-80 ksi tensile. ASTM A325 high-strength bolts: 92 ksi proof load. AISC steel construction tables, FAA/MIL-SPEC aerospace allowables, and ASME Section VIII pressure vessel design all use ksi. Fracture toughness (K_IC) for steels: 50-200 ksi·√in. Convenient because it keeps large structural stresses as manageable 3-digit numbers. 1 ksi = 6.895 MPa.
