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 Object Pascal and C the ASCII character set codice_47 and codice_48 is a TAB character. In addition to codice_49 type, Object Pascal also has codice_50 to represent Unicode characters. In C, this is usually implemented as a macro or codice_16 with name codice_52, which is simply an alias for codice_24. In Pascal, boolean is an enumerated type. The possible values of boolean are false and true, with ordinal value of false=0 and true=1, other values are undefined. For conversion to integer, ord is used: There is no standard function for integer to boolean, however, the conversion is simple in practice: C has binary valued
