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.
Kilonewton/square Meter
A kilonewton per square meter (kN/m^2) is a unit of pressure equivalent to one kilonewton of force applied over an area of one square meter.
History/Origin
The kilonewton per square meter is derived from the SI units of force (newton) and area (square meter). It has been used in engineering and scientific contexts to measure pressure, especially in fields like civil and mechanical engineering, since the adoption of the SI system.
Current Use
Today, kN/m^2 is commonly used in engineering to specify stress, pressure, and load measurements, often interchangeably with the Pascal (Pa), where 1 kN/m^2 equals 1,000 Pa.
