Conversion Formula
ftH₂O = kbar × 33455.25633
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 Feet of Water
One foot of water column (ftH₂O) ≈ 2,989 Pa - the US customary equivalent of cmH₂O used in civil and hydraulic engineering. Municipal water supply systems are designed for 40-80 psi head ≈ 92-184 ft; fire suppression sprinkler systems require minimum 7 psi ≈ 16 ft. Well pump specifications, sump pump head ratings, irrigation mainline pressure, and drainage calculations all use feet of head. 1 ft of water = 12 in WC = 0.4335 psi ≈ 2,989 Pa.
