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
Vector Pascal Vector Pascal Vector Pascal is an open source compiler that extends the Pascal programming language. It is designed to support efficient expression of algorithms using the SIMD model of computation. It imports into Pascal abstraction mechanisms derived from Iverson's APL programming language. In particular it extends all operators to work on vectors of data. The type system is also extended to handle pixels and dimensional analysis. The compiler is implemented in Java. The syntax generally follows that of Turbo Pascal and includes all features of the ISO standard (ISO 7185-1990) except where overridden by Turbo Pascal. Features of Extended Pascal
