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.
Centimeter Mercury (0°c)
Centimeter mercury (0°C) is a unit of pressure measurement representing the pressure exerted by a one-centimeter column of mercury at 0°C.
History/Origin
The centimeter mercury was historically used in barometry and pressure measurements before the adoption of the pascal. It originated from the use of mercury columns in barometers to measure atmospheric pressure, with the unit reflecting the height of the mercury column.
Current Use
Today, the centimeter mercury is largely obsolete and replaced by SI units like the pascal. However, it is still used in some medical and historical contexts to measure blood pressure and atmospheric pressure in certain regions.
