Inch Mercury (32°f)
Inch of mercury at 32°F (inHg) is a unit of pressure measurement representing the height of a mercury column in inches, used primarily in meteorology and aviation.
History/Origin
The inch of mercury originated from barometric pressure measurements using a mercury barometer, with its use dating back to the 18th century. It became a standard unit in weather reporting and altitude measurement.
Current Use
Today, inHg is primarily used in meteorology to report atmospheric pressure, especially in the United States, and in aviation for altitude and pressure readings.
Millipascal
A millipascal (mPa) is a unit of pressure equal to one thousandth of a pascal, the SI unit of pressure.
History/Origin
The millipascal is derived from the pascal, which was named after Blaise Pascal. It is used in contexts requiring very small pressure measurements, but its usage is relatively uncommon due to the widespread adoption of the pascal.
Current Use
Millipascals are primarily used in scientific and engineering fields to measure very low pressures, such as in fluid dynamics, vacuum systems, and sensitive instrumentation within the 'Pressure' converter category of 'Common Converters'.
