Using a mercury density of 13,595.1 kg/m³ at 0 degC, water density of 1000 kg/m³ and standard gravity of 9.80665 m/s² to determine the pressure generated by 1 mmHg and 1 mmH2O in SI units, a vacuum pressure in millimeters of water column can be converted to millimetres of mercury column using the calculation below:
- 1 mmHg = 133.322 pascals (Pa)
- 1 mmH2O = 9.80665 pascals (Pa)
- mmHg value x 133.322 Pa = mmH2O value x 9.80665 Pa
- mmHg value = mmH2O value x 0.0735559
