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 Standard Atmosphere?
The standard atmosphere (symbol: atm) is a non-SI unit of pressure defined as exactly 101,325 pascals. It represents the average atmospheric pressure at sea level under standard conditions and is widely used in chemistry, physics, meteorology, and engineering. The standard atmosphere provides a convenient reference for pressure measurements and scientific calculations. Additional information is available in the standard atmosphere reference.
One standard atmosphere is equal to 101,325 pascals, 1.01325 bars, 101.325 kilopascals, 14.6959 pounds per square inch, and 760 millimeters of mercury. The standard atmosphere is one of the most important reference units in science and engineering.
