Bar (unit) (symbol: cbar), and millibar (symbol: mbar or mb). The notation bar(g), though deprecated by various bodies, represents gauge pressure, i.e., pressure in bars above ambient or atmospheric pressure. The bar is defined using the SI derived unit, pascal: ≡ 100,000 Pa ≡ 100,000 N/m. Thus, is equal to: and 1 bar is approximately equal to: Notes: The word "bar" has its origin in the Greek word (), meaning weight. The unit's official symbol is bar; the earlier symbol b is now deprecated and conflicts with the use of b denoting the unit barn, but it is still encountered, especially as
Comparison of Pascal and Delphi does not go into Delphi-specific extensions to the language, which are numerous and still increasing. 1. The way procedures and functions can be passed as parameters differs: Delphi requires explicit procedural types to be declared where Standard Pascal does not. 2. Delphi does not support so called 'extraprocedural gotos', in which goto statements may reference targets outside the current procedure/function body. 3. Standard Pascal has file 'buffer variables', together with 'get' and 'put' standard procedures that operate on them. Neither are supported in Delphi. 4. Given a variant record in Standard Pascal, the size of a particular variant can be
