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.
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.
