Centimeter Water (4°c)

Centimeter water (4°C), symbol cmH2O, is a unit of pressure representing the pressure exerted by a one-centimeter column of water at 4 degrees Celsius.

History/Origin

The centimeter water was developed as a practical unit of pressure measurement in medical and engineering contexts, especially for low-pressure measurements such as respiratory and fluid pressure, originating from the use of water columns in manometers.

Current Use

It is primarily used in medical settings to measure intracranial pressure, respiratory pressures, and other low-pressure applications where precise measurement of small pressure differences is required.


Atmosphere Technical

The atmosphere technical (at) is a unit of pressure defined as exactly 101,325 pascals, representing the average atmospheric pressure at sea level.

History/Origin

The atmosphere technical was established as a standard unit of pressure in the early 20th century to facilitate scientific and engineering calculations involving atmospheric pressure, aligning with the international standard atmosphere (ISA).

Current Use

It is primarily used in scientific, meteorological, and engineering contexts to quantify atmospheric pressure, especially in fields requiring standardized pressure measurements at sea level.
