Convert millimeter water (4°C) to centimeter mercury (0°C)

Please provide values below to convert millimeter water (4°C) [mmH2O] to centimeter mercury (0°C) [cmHg], or Convert centimeter mercury (0°C) to millimeter water (4°C).

1 mmH2O = 0.00735538885904 cmHg. To convert millimeter water (4°C) to centimeter mercury (0°C), multiply the value by 0.00735538885904; to go the other way, divide by it (1 cmHg = 135.954742729 mmH2O). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Millimeter Water (4°c)

Millimeter water (4°C) is a unit of pressure measuring the height of a water column at 4 degrees Celsius that exerts a specific pressure.

History/Origin

The unit originated from the use of water columns to measure pressure, particularly in hydrology and medical applications, with standardization based on the density of water at 4°C.

Current Use

It is primarily used in medical and scientific contexts to measure low pressures, such as intracranial pressure, respiratory pressures, and in calibration of pressure sensors.


Centimeter Mercury (0°c)

Centimeter mercury (0°C) is a unit of pressure measurement representing the pressure exerted by a one-centimeter column of mercury at 0°C.

History/Origin

The centimeter mercury was historically used in barometry and pressure measurements before the adoption of the pascal. It originated from the use of mercury columns in barometers to measure atmospheric pressure, with the unit reflecting the height of the mercury column.

Current Use

Today, the centimeter mercury is largely obsolete and replaced by SI units like the pascal. However, it is still used in some medical and historical contexts to measure blood pressure and atmospheric pressure in certain regions.
