mmH2O to Pa (pascals) Conversion Table

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

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