Atmosphere (unit) for the purposes of specifying the physical properties of substances, “"standard pressure"” should be precisely . A pressure of 1 atm can also be stated as: Scuba divers and others use the word "atmosphere" and "atm" in relation to pressures that are relative to mean atmospheric pressure at sea level (1.013 bar). For example, a partial pressure of oxygen is calibrated typically using air at sea level, so is expressed in units of atm. The old European unit technical atmosphere (at) is equal to 1 kilogram-force per square centimetre (kgf/cm), Pa. Atmosphere (unit) The standard atmosphere (symbol: atm) is a
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
