Standard temperature and pressure

In order to be able to reproduce experiments, standard conditions for temperature and pressure have been defined in different fields of science. Very often these are also called standard temperature and pressure. The table below gives some examples:

Domain	Temperature	Pressure	Defined by
Physics	273.15 K (0 °C, 32 °F)[1]	101.325 Pa	DIN 1343
Chemistry	298.15 K = 25 °C[2]	1 bar / 100 kPa	IUPAC
Airline industry	15 °C	1013,25 hPa, at sea level
