Newton/square Meter
The newton per square meter (N/m²) is the SI derived unit of pressure, representing the force of one newton applied over an area of one square meter.
History/Origin
The unit was established as part of the International System of Units (SI) in 1960, replacing earlier units like the pascal, which is now the standard SI unit for pressure.
Current Use
N/m², or pascals (Pa), is widely used in science, engineering, and meteorology to measure pressure, stress, and related quantities.
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.
