Bar (unit) mb (rather than the proper mbar) to denote the millibar. Between 1793 and 1795, the word bar was used for a unit of weight in an early version of the metric system. Atmospheric air pressure is often given in millibars, where standard atmospheric pressure at sea level is defined as 1013.25 mbar, 101.325 kPa, 1.01325 bar, which is about . Despite the millibar not being an SI unit, meteorologists and weather reporters worldwide have long measured air pressure in millibars as the values are convenient. After the advent of SI units, some meteorologists began using hectopascals (symbol hPa) which are
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
