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
Turbo Pascal like the object files used in other languages such as FORTRAN or C. For example, the line codice_1 in a program included the unit called crt; the codice_2 is the mechanism for using other compilation units. codice_3 and codice_4 were the keywords used to specify, within the unit, what was (and what was not) visible outside the unit. This is similar to the codice_5 and codice_6 keywords in other languages such as C++ and Java. Units in Borland's Pascal were similar to Modula-2's separate compilation system. In 1987, when Turbo Pascal 4 was released, Modula-2 was making inroads as an
