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

Enter a pressure in Pa below to convert it to the equivalent pressure in mmH₂O 4°C.
