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
IP Pascal ISO 7185 standard compilers were used, ending with the SVS Pascal compiler, a 32 bit DPMI extender based implementation. By 1993, ISO 7185 compatible compilers that delivered high quality 32 bit code were dying off. At this point, the choice was to stop using Pascal, or to revive the former IP Pascal project and modernize it as an 80386 compiler. At this point, a Pascal parser, and assembler (for Z80) were all that existed which were usable on the IBM-PC. From 1993 to 1994, the assembler was made modular to target multiple CPUs including the 80386, a linker to replace
