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 coupled to output into a graphical window. Example: "hello world" with graphical commands added. Note that standard Pascal output statements are still used. Because IP Pascal modules can "override" each other, a graphical extension module (or any other type of module) can override the standard I/O calls implemented in a module below it. Thus, paslib implements standard Pascal statements such as read, write, and other support services. gralib overrides these services and redirects all standard Pascal I/O to graphical windows. The difference between this and such libraries in other implementations is that you typically have to stop using the standard
