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
