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 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.
What is Decipascal?
The decipascal (symbol: dPa) is an SI-derived unit of pressure equal to one-tenth (0.1) of a pascal. It is used for measuring small pressure differences in scientific research, environmental monitoring, and precision instrumentation. The decipascal follows the SI metric prefix system, where the prefix deci represents one-tenth.
One decipascal is equal to 0.1 pascal, 10 centipascals, 100 millipascals, 0.000001 bar, and 9.86923×10-7 standard atmosphere. The decipascal is suitable for representing small pressure values while remaining within the SI system.
