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
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
