[edit] Error in definition

Standard Atmosphere is not a unit of pressure! Standard Atmosphere refers to pression of 101 325 Pa. See http://goldbook.iupac.org/S05906.html

Note the bit on that page where it says "used as unit of pressure with the symbol atm..." --Calair 17:43, 30 April 2007 (UTC)
"Standard atmosphere (symbol: atm) is a unit of pressure". Why not? "as unit of pressure with the symbol" . Contributions from (user:Mago® - Wiki-pt) —The preceding unsigned comment was added by 200.161.58.39 (talk) 23:19, 30 April 2007 (UTC).
I'm really not seeing a meaningful difference between "is a unit of pressure" and "is used as a unit of pressure". --Calair 02:51, 1 May 2007 (UTC)

Hi Calair. The problem is:

"Standard atmosphere (symbol: atm) is a unit of pressure..."

Traduction: Standard atmosphere = unit

Comments: No. Unit = atm, Pa, ºC, ºF, K. The value 101 325 Pa is a pressure used as unit of pressure.



  • IUPAC:

Pressure defined as 101 325 Pa and used as unit of pressure with the symbol atm.

Traduction: Standad atmosphere = Pressure = 101 325 Pa.


Sorry for my bad English. ;(

Hi Calair.

Standard Atmosphere = 101 325 Pa = Normal.

The normal term means a value at a pressure of 101 325 Pa too.

Add this information for me in Wiki-en. ;) Thanks


Please... do you speak portuguese? YES ( ) No ( ) ?

I don't speak Portuguese, so I don't know if there's a translation problem here, but 'atm' and 'standard atmosphere' are simply different ways of referring to the same unit, in the same way that 'Pa' is an abbreviated version of 'Pascal'. Maybe you're getting confused with SI units? A standard atmosphere isn't a SI unit, but it most certainly is a unit of pressure. --Calair 14:29, 1 May 2007 (UTC)
