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.
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.
