FAQ
What is the conversion factor from bar to ftH₂O?
1 bar equals 33.45526 ftH₂O. To convert, multiply the value in bar by 33.45526.
How do I convert 1 bar to ftH₂O?
1 bar = 33.4553 ftH₂O. For any value, multiply by 33.45526.
How do I convert ftH₂O back to bar?
Divide by the same factor — or equivalently, multiply by 0.02989067. So 1 ftH₂O = 0.0298907 bar.
When would I need to convert bar to foot of water column (4 °C)?
Pressure conversions between bar and ftH₂O are common when working with mixed-vendor instrumentation, when piping codes use different units to process datasheets, or when converting field readings into SI for hydraulic calculations.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
