Convert Kilobars (kbar) to Centimeters of Water (cmH₂O) instantly and accurately.
Conversion Formula
cmH₂O = kbar × 1019716.213
About Kilobars
A kilobar (kbar) = 1,000 bar = 100 MPa = 10⁸ Pa - standard in high-pressure geophysics and experimental petrology. Earth mantle phase transitions: olivine → wadsleyite at ~130-140 kbar (410 km depth); post-spinel transition at ~230 kbar (660 km). Diamond anvil cells routinely reach 100-400 kbar for materials synthesis and equation-of-state measurement. High-pressure synthesis of cubic boron nitride (~50 kbar) and superhard materials uses large-volume presses. Explosive shock pressures for mining and demolition: 100-1,000 kbar. 1 kbar = 100 MPa.
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.
