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.
Terapascal
A terapascal (TPa) is a unit of pressure equal to one trillion pascals (10^12 Pa).
History/Origin
The terapascal was introduced as part of the International System of Units (SI) to measure extremely high pressures, especially in scientific research involving materials under extreme conditions, such as in geophysics and high-energy physics.
Current Use
The terapascal is used in scientific fields to quantify very high pressures, such as in studying Earth's deep interior, material science, and high-pressure physics experiments.
