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]
To head off further controversy about this, I re-quote the excerpt from The International System of Units brochure already quoted at Pascal (unit)#Origin: When an SI unit is spelled out in English, it should always begin with a lowercase letter (pascal), except where any word would be capitalized, such as at the beginning of a sentence or in ...
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 ...
