Oddly enough the SI unit is Pascal (Pa) or N/m2, not atmosphere. The technical atmosphere is: around 98KPa, it's not really metric.

- ygra 12y agokPa. Otherwise it'd be Kelvinpascals. And while pressure is often said to be x atmospheres, they usually use bar, which is an SI-derived unit (equal to 10⁵ Pa), which is close enough to the old usage of atmospheres. There seem to have been two different atmospheres that were pretty close anyway. One being defined as air pressure at sea level, the other being defined as the pressure of 10 meters of water.
- xxs 12y ago>>kPa. Otherwise it'd be Kelvinpascals. Great observation! I guess I am way too used to KB and in that very case KPa would be 1024Pa which is even worse. Have an upvote.
- ygra 12y agoThat'd be KiPa, then (kibipascals) ;) Standardised since 1999, I think. But no one really uses it. Kilobytes would technically be kB as well.
- skrause 12y agoThe most used unit for pressure used in Germany is bar (= 100 kPa) so that you don't have to deal with really big numbers all the time: https://en.wikipedia.org/wiki/Bar_(unit) https://en.wikipedia.org/wiki/Bar_(unit)
