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
Smart Pascal several differences that clearly separate the dialect from standard Object Pascal: In Object Pascal a property is an exposed value that can either be linked to a class-field or a class-member method. This is the traditional way of exposing a value property, where the consumer of the property is abstracted from the reader and writer logic. The consumer does not know if the property is explicitly linked to a field or a writer method. Smart Pascal has full support for the older paradigm but introduces a technique called "property expressions". It basically allows you to program reader and writer logic
