| <onlyinclude>'''Standard conditions for temperature and pressure''' (STP) are set standard conditions for the measurement and documentation of chemical and physical processes.</onlyinclude><ref>Engineering toolbox, ''STP - Standard Temperature and Pressure'' [Online], Available: http://www.engineeringtoolbox.com/stp-standard-ntp-normal-air-d_772.html</ref> Since [[temperature]] and [[pressure]] vary in all locations on the globe, it is necessary to have a base foundation for comparing different sets of data to. The conditions set by STP is a temperature of 273.15 [[Kelvin|K]] ([[celsius|0°C]] or [[fahrenheit|32°F]]) and a pressure of 10<sup>5</sup> [[Pascal]]s (formerly 1 [[atm]], but IUPAC has since changed this standard).<ref>IUPAC, ''STP'' [Online], Available: http://goldbook.iupac.org/S06036.html</ref>

| Since a [[gas]]' [[volume]] depends on the temperature and pressure, at STP conditions one [[mole]] of an [[ideal gas law|ideal gas]] has a volume of 22.4 [[liter]]s.
