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
IP Pascal ISO 7185 standard compilers were used, ending with the SVS Pascal compiler, a 32 bit DPMI extender based implementation. By 1993, ISO 7185 compatible compilers that delivered high quality 32 bit code were dying off. At this point, the choice was to stop using Pascal, or to revive the former IP Pascal project and modernize it as an 80386 compiler. At this point, a Pascal parser, and assembler (for Z80) were all that existed which were usable on the IBM-PC. From 1993 to 1994, the assembler was made modular to target multiple CPUs including the 80386, a linker to replace
