Pa (pascals) to mmH2O Conversion Table

A low range air pressure reading in pascals can be converted to millimetres of water using the following method:

• 1 mmH₂O = 9.80665 pascals (Pa)
• 1 Pa = 1 pascals (Pa)
• mmH₂O value x 9.80665 Pa = pascal value x 1 Pa
• mmH₂O value = Pa value x 0.101972

• Pass/Fail timed 500 kPa pressure leak test software and sensor
• 600 bar, 9000 psi, 60 MPa Pressure Sensors, Transducers & Transmitters
• 350 bar, 5000 psi, 35 MPa Pressure Sensors, Transducers & Transmitters
• 700 bar, 10000 psi, 70 MPa Pressure Sensors, Transducers & Transmitters
