Pascal (unit) dB SPL, or 20 µPa. The airtightness of buildings is measured at 50 Pa. The units of atmospheric pressure commonly used in meteorology were formerly the bar, which was close to the average air pressure on Earth, and the millibar. Since the introduction of SI units, meteorologists generally measure pressures in hectopascals (hPa) unit, equal to 100 pascals or 1 millibar. Exceptions include Canada, which use kilopascals (kPa). In many other fields of science, the SI is preferred, which means Pa with a prefix (in multiples of 1000) is preferred. Many countries also use the millibars. In practically all other
Comparison of Pascal and Delphi Rewrite() results in an error, where under Standard Pascal it opens a temporary file that exists for the duration of the program before being automatically deleted. 10. Notwithstanding the fact Delphi still allows using much of the traditional Pascal RTL, Delphi-specific library functionality is generally implemented in ordinary Delphi code that uses, rather than adds to, compiler-provided intrinsics. This philosophy contrasts to Standard Pascal, whose RTL must be provided by the compiler. For example, in Standard Pascal, the 'file' type is an intrinsic type - sort of like a record, but another compiler-defined type alongside records. In contrast, the TFileStream
