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.
Terapascal
A terapascal (TPa) is a unit of pressure equal to one trillion pascals (10^12 Pa).
History/Origin
The terapascal was introduced as part of the International System of Units (SI) to measure extremely high pressures, especially in scientific research involving materials under extreme conditions, such as in geophysics and high-energy physics.
Current Use
The terapascal is used in scientific fields to quantify very high pressures, such as in studying Earth's deep interior, material science, and high-pressure physics experiments.
