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
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
