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
Pascal (programming language) UCSD language features survive today, including in Borland's dialect. In 1990, an extended Pascal standard was created as ISO/IEC 10206, which is identical in technical content<ref name="ISO/ANSI identical"></ref> to IEEE/ANSI 770X3.160-1989 Niklaus Wirth's Zurich version of Pascal was issued outside ETH in two basic forms, the CDC 6000 compiler source, and a porting kit called Pascal-P system. The Pascal-P compiler left out several features of the full language. For example, procedures and functions used as parameters, undiscriminated variant records, packing, dispose, interprocedural gotos and other features of the full compiler were omitted. UCSD Pascal, under Professor Kenneth Bowles, was based
