Newton/square Centimeter
The newton per square centimeter (N/cm²) is a unit of pressure representing the force of one newton applied over an area of one square centimeter.
History/Origin
The unit derives from the SI unit of force, the newton, combined with the centimeter as a unit of area. It has been used in fields like engineering and physics to measure pressure, especially in contexts where the centimeter is a convenient unit of length. Its usage predates the widespread adoption of the pascal (Pa), which is equivalent to N/m².
Current Use
The N/cm² is still used in certain engineering and industrial applications, particularly in contexts where pressure measurements are expressed in centimeters rather than meters. It is also used in some scientific fields for convenience, though the pascal is more common internationally.
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.
