Convert Pounds per Square Foot to Terapascals
Convert Pounds per Square Foot (lbf/ft²) to Terapascals (TPa) instantly and accurately.
Conversion Formula
TPa = lbf/ft² × 4.788025898e-11
About Pounds per Square Foot
One pound per square foot (psf) ≈ 47.88 Pa - the standard structural engineering load unit in US practice. Building codes specify design loads in psf: residential floors 40 psf; office buildings 50-80 psf; assembly areas 100+ psf; snow loads can exceed 100 psf. Wind pressure on building facades, soil bearing capacity for shallow foundations, and lateral earth pressure in retaining walls are all in psf. The related unit ksf (1,000 psf = 47.88 kPa) covers higher-capacity soils and deep foundations. 1 psf = 47.88 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.
