What is Millimetre of Water Column (mmWC)
The Millimetre of water column (mmWC) is a unit of pressure measurement, and it is defined as the pressure exerted by a column of water at 4 degree celcius. This calculation is mainly used in laboratory applications, Ventilation and Air conditioning.
Millimetre of Water Column (mmWC) to Millimetre of Mercury (mmHg) Pressure Unit Conversion Formula
mmHg=mmWC×0.073556
Where 0.073556 is the conversion factor between the mmWC and mmHg. To find the mmHg the known value of mmWC is multiplied with the conversion factor value.

Example Calculation Using Formula
If you have 100 mmWC value , Then you can convert it to mmHg using the formula:
- where mmHg = ?
- mmWC = 100
- and conversion factor is 0.073556
mmHg=100×0.073556=7.3556 mmHg
