What is Pressure?
Pressure is the force applied perpendicular to a surface per unit area: P = F / A. The SI unit is the pascal (Pa), equal to one newton per square metre (1 Pa = 1 N/m²). Practical applications use larger units: the bar (1 bar = 100,000 Pa, close to standard atmospheric pressure), atmosphere (atm) (1 atm = 101,325 Pa), and psi (pounds per square inch, used in the US for tire and gas pressures). Blood pressure is measured in mmHg (millimetres of mercury), also called torr.
What is Technical Atmosphere?
Technical atmosphere (symbol: at) is a unit of pressure defined as the pressure exerted by one kilogram-force per square centimeter. One technical atmosphere is exactly equal to 98,066.5 pascals, 0.980665 bar, or 0.967841 standard atmosphere (atm). The technical atmosphere was widely used in engineering, hydraulics, and industrial pressure measurements, particularly in Europe, before SI units became the international standard. It is still encountered in older engineering documents and is commonly converted to pascals, bar, and standard atmospheres when interpreting historical specifications and technical data.
What is Inch of mercury?
The inch of mercury (symbol: inHg) is a non-SI unit of pressure based on the height of a mercury column one inch high under standard gravity. It is widely used in aviation, meteorology, and vacuum measurement, particularly in the United States and Canada. Although the pascal is the SI unit of pressure, the inch of mercury remains an important unit in many industries. More information is available in the inch of mercury reference.
One inch of mercury is equal to 3,386.39 pascals, 3.38639 kilopascals, 0.0338639 bar, 0.491154 psi, and 25.4 millimeters of mercury. The inch of mercury is commonly used for barometric pressure and vacuum measurements.
