Talk:Normal temperature and pressure

From my university education, I understood STP to always be 0°C but the company with whom I now work have NTP quoted as 0°C in one of the company design manuals.

Can anyone offer any insight into why there is this discrepancy?

I believe .. STP is 25 deg C and NTP is 0 deg C —Preceding unsigned comment added by Orfintain (talk • contribs) 14:07, 7 May 2009 (UTC)
