Pressure - Wikipedia
网页Various units are used to express pressure. Some of these derive from a unit of force divided by a unit of area; the SI unit of pressure, the pascal (Pa), for example, is one newton per square metre (N/m 2); similarly, the pound-force per square inch (psi, symbol lbf/in 2) is the traditional unit of pressure in the imperial and US customary ...
What is the Unit Of Pressure? - SI Unit, CGS Unit, MKS Unit
网页The SI unit of pressure is pascal (represented as Pa) which is equal to one newton per square metre (N/m 2 or kg m -1 s -2). Interestingly, this name was given in 1971. Before that pressure in SI was measured in newtons per square metre.
13.4: Pressure Units and Conversions - Chemistry LibreTexts
网页The pascal \(\left( \text{Pa} \right)\) is the standard unit of pressure. A pascal is a very small amount of pressure, so the most useful unit for everyday gas pressures is the kilopascal \(\left( \text{kPa} \right)\).
Pascal (unit) - Wikipedia
网页The pascal (symbol: Pa) is the unit of pressure in the International System of Units (SI). It is also used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength. The unit, named after Blaise Pascal, is an SI coherent derived unit defined as one newton per square metre (N/m 2). [1] .

Units of Measurement/Pressure - Wikibooks
网页2019年10月24日 · Pressure is the force per unit area applied in the direction perpendicular to a surface. Mathematically, pressure is defined as. where: P is pressure. F is the component of force perpendicular to the surface. A is the area of the surface. When a force is constant over an area, the pressure acting on that area is simply.
Pressure conversion
网页The most commonly used metric unit of pressure is the Pascal (Pa), which is defined as one Newton per square meter. This unit is named after the French mathematician and physicist Blaise Pascal, who made significant contributions to the study of fluid mechanics.
