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
Turbo Pascal like the object files used in other languages such as FORTRAN or C. For example, the line codice_1 in a program included the unit called crt; the codice_2 is the mechanism for using other compilation units. codice_3 and codice_4 were the keywords used to specify, within the unit, what was (and what was not) visible outside the unit. This is similar to the codice_5 and codice_6 keywords in other languages such as C++ and Java. Units in Borland's Pascal were similar to Modula-2's separate compilation system. In 1987, when Turbo Pascal 4 was released, Modula-2 was making inroads as an
