Convert Feet of Water to Barye
Convert Feet of Water (ftH₂O) to Barye (Ba) instantly and accurately.
Conversion Formula
Ba = ftH₂O × 29890.6692
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.
About Barye
The barye (Ba) is the CGS unit of pressure - 1 dyne/cm² = exactly 0.1 Pa = 1 µbar. Standard atmosphere = 1,013,250 Ba. It dominated physics and laboratory science from the mid-19th century until SI adoption. Legacy acoustic CGS literature used 1 barye (0.1 Pa) as the underwater reference pressure, creating a 100 dB offset versus the modern 1 µPa reference - a critical correction when comparing historical and modern underwater acoustics databases. Still encountered in classical fluid mechanics derivations and early 20th-century meteorological literature. 1 Ba = 0.1 Pa.
