Millimeter Mercury (0°c)
Millimeter mercury (0°C), abbreviated as mmHg, is a unit of pressure measurement based on the height of a column of mercury in millimeters at 0°C under standard gravity.
History/Origin
The mmHg originated from the use of mercury barometers in the 17th century to measure atmospheric pressure. It became a standard unit in meteorology and medicine for measuring blood pressure and other pressure-related phenomena.
Current Use
Today, mmHg is primarily used in medicine to measure blood pressure and in meteorology for atmospheric pressure readings. It is also used in various scientific and industrial applications where precise pressure measurements are 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.
