Millimeter Water (4°c)
Millimeter water (4°C) is a unit of pressure measuring the height of a water column at 4 degrees Celsius that exerts a specific pressure.
History/Origin
The unit originated from the use of water columns to measure pressure, particularly in hydrology and medical applications, with standardization based on the density of water at 4°C.
Current Use
It is primarily used in medical and scientific contexts to measure low pressures, such as intracranial pressure, respiratory pressures, and in calibration of pressure sensors.
Kilopascal
The kilopascal (kPa) is a unit of pressure equal to 1,000 pascals, where one pascal is defined as one newton per square meter.
History/Origin
The kilopascal was introduced as part of the metric system to provide a convenient unit for measuring pressure, especially in scientific and engineering contexts, replacing larger units like the bar in many applications.
Current Use
The kilopascal is widely used today in various fields such as meteorology, engineering, and physics to measure pressure, including tire pressure, blood pressure, and atmospheric pressure.
