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
Smart Pascal support anonymous methods, but Smart Pascal has one advantage over these native compilers. Under native Pascal (compilers that produce executable machine code), you have class procedures and ordinary procedures. The only difference between these two is that if you want to reference the first (class method) you must postfix the declaration with "of object". This way of referencing a class method is typically used for event declarations. An event is declared thus in ordinary Object Pascal: If you omit the "of object" postfix, the reference can only be used on procedures and functions on unit level. The compiler does not
