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
