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 |
