Pascal (unit) Pascal (unit) The pascal (symbol: Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is defined as one newton per square metre. It is named after the French polymath Blaise Pascal. Common multiple units of the pascal are the hectopascal (1 hPa = 100 Pa) which is equal to one millibar, and the kilopascal (1 kPa = 1000 Pa) which is equal to one centibar. The unit of measurement called standard atmosphere (atm) is defined as . Meteorological reports typically state atmospheric pressure in millibars. The unit is
Pascal (programming language) UCSD language features survive today, including in Borland's dialect. In 1990, an extended Pascal standard was created as ISO/IEC 10206, which is identical in technical content<ref name="ISO/ANSI identical"></ref> to IEEE/ANSI 770X3.160-1989 Niklaus Wirth's Zurich version of Pascal was issued outside ETH in two basic forms, the CDC 6000 compiler source, and a porting kit called Pascal-P system. The Pascal-P compiler left out several features of the full language. For example, procedures and functions used as parameters, undiscriminated variant records, packing, dispose, interprocedural gotos and other features of the full compiler were omitted. UCSD Pascal, under Professor Kenneth Bowles, was based
