Centimeter Water (4°C) : A centimetre of water or centimeter of water(abbreviated cmH2O or cm H2O) is a less commonly used unit of pressure. It is defined as the pressure exerted by a column of water of 1 cm in height at 4 °C (temperature of maximum density) at the standard acceleration of gravity.

Millimeter Mercury (0°C) : Millimeter of mercury is a small pressure unit which represents the pressure pushing down due to gravity of any volume of liquid mercury which is 1mm high. It is widely used, and its value is approximately equal to a pressure of 1 torr.

### FAQ about cmAq to mmHg Conversion

1 centimeter water (cmAq) is equal to 0.73554 millimeter mercury (0°c) (mmHg).

1cmAq = 0.73554mmHg

The pressure p in millimeter mercury (0°c) (mmHg) is equal to the pressure p in centimeter water (4°c) (cmAq) times 0.73554, that conversion formula:

p(mmHg) = p(cmAq) × 0.73554

One Centimeter Water is equal to 0.73554 Millimeter Mercury (0°C):

1cmAq = 1cmAq × 0.73554 = 0.73554mmHg

One Millimeter Mercury is equal to 1.35955 Centimeter Water (4°C):

1mmHg = 1mmHg × 1.35955 = 1.35955cmAq

p(mmHg) = 5(cmAq) × 0.73554 = 3.6777mmHg
