💧 psi → inH₂O Conversion
Express psi values as inches of water column for HVAC and process control.
Inches of water column are common in ventilation, gas delivery, and filter monitoring. This converter translates psi readings into inHâ‚‚O plus SI units.
Inches of water: 27.6799 inHâ‚‚O
Pascals: 6,894.76 Pa
Kilopascals: 6.8948 kPa
How to Use This Calculator
Enter psi
Type the pressure measured in psi.
Review inHâ‚‚O
The converter multiplies psi by 27.7076 to output inches of water column.
Check SI references
Pascals and kPa help when referencing instrumentation specs.
Formula
inH₂O ≈ psi × 27.7076
Pa ≈ psi × 6,894.757
kPa = Pa ÷ 1,000
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Inches of water column are widely used to describe small differential pressures in HVAC ducts and gas piping. This converter keeps your psi readings compatible with those standards without manual calculations.
The SI outputs let you document the same pressure in metric units for international teams.
