Pressureis the force applied over an area. In the meter-kilogram-second system, it is expressed in pascals. Specifically, a pascal measures the pressure applied by 1 N of force applied on an area of 1 m2at a right angle. SI accepted it as the standard unit of pressure in 1971 and nam...
Learn to define what pressure is. Discover the SI unit for pressure, see the pressure formula, learn what a pascal is, and view examples calculating pressure. What is Pressure? Pressure, symbolized as p or P, refers to the force applied per unit area. Force should always be applied perpe...

Primary state reference standard for the unit of pressure — The pascaldoi:10.1007/BF01100937Investigations of the primary state standard for the unit of pressure carried out at the VNIIM have led to the following conclusions. The primary state standard of the unit of pressure, the pascal, ...
Units of Pressure: Pascal (Pa), Newton per meter square, bar, torr, atm (atmospheric pressure) are the measurable units of the pressure. Where, the unit pascal is also equal to {eq}{\rm{kg/m}} \cdot {{\rm{s}}^{\rm{2}}} {/eq} in international stan...
1.The unit of pressure produced when one newton acts on about 1 sq m. 2.(Pa) A unit of pressure equal to the force of one newton acting over an area of one square meter. 3.A high-level, general-purpose programming language.
a unit of pressure in the mks system equivalent to one newton per square meter or to 1.45 × 10−4 pounds per square inch pascal 例句 1.Pascal went further than simply insisting on the authority of experience; he argued that our knowledge of nature is capable of endless progress because ...
squared in base units or Newtons per square meter, are an SI unit of pressure – a metric unit of pressure. There are many other units that can describe pressure from millibars to psi (pounds per square inch), but all of them describe some amount of force distributed over a certain ...
