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.
Megapascal
The megapascal (MPa) is a unit of pressure equal to one million pascals, where one pascal (Pa) is the pressure exerted by a force of one newton per square meter.
History/Origin
The megapascal was introduced as part of the International System of Units (SI) to provide a convenient scale for measuring high pressures, especially in engineering and scientific applications, replacing larger units like the bar in many contexts.
Current Use
The MPa is widely used today in engineering, material science, and industrial applications to specify pressures in fields such as hydraulics, pneumatics, and structural engineering.
