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.
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.
