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.
Dekapascal
The dekapascal (daPa) is a unit of pressure equal to ten pascals, where one pascal (Pa) is the SI derived unit of pressure representing one newton per square meter.
History/Origin
The dekapascal was introduced as a metric prefix-based unit to simplify the expression of larger pressures, particularly in fields like meteorology and engineering, aligning with the SI system's prefixes. Its usage is relatively uncommon compared to the pascal.
Current Use
The dekapascal is occasionally used in scientific and technical contexts to express pressure measurements more conveniently, especially in applications where pressures are in the range of thousands of pascals. It is part of pressure conversions within the 'Common Converters' category.
