Convert Centimeters of Water to Terapascals
Convert Centimeters of Water (cmH₂O) to Terapascals (TPa) instantly and accurately.
Conversion Formula
TPa = cmH₂O × 9.806650000e-11
About Centimeters of Water
One centimetre of water column (cmH₂O) ≈ 98.07 Pa - the clinical pressure unit for respiratory and intravascular measurements. Mechanical ventilator settings are in cmH₂O: peak inspiratory pressure (PIP) 15-30 cmH₂O; PEEP 5-15 cmH₂O; plateau pressure should stay below 30 cmH₂O to avoid lung injury. Lumbar puncture CSF opening pressure is normally 8-20 cmH₂O. CPAP/BiPAP therapy for sleep apnea: 4-20 cmH₂O. Central venous pressure is also reported in cmH₂O. 1 cmH₂O = 98.0665 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.
