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.
Inch Water (4°c)
Inch water (4°C) is a unit of pressure measurement representing the pressure exerted by a one-inch column of water at 4 degrees Celsius.
History/Origin
The inch water (4°C) has been used historically in engineering and meteorology to measure low-pressure differences, especially in ventilation and HVAC systems, as a practical alternative to more complex units.
Current Use
Today, inch water (4°C) is primarily used in the United States for measuring low-pressure differences in HVAC, ventilation, and fluid systems, serving as a standard unit in these fields within the pressure converter category of common converters.
