After IUPAC (International Union of Pure and Applied Chemistry) the standard temperature is 273,15 K (or 0 0C) and the standard pressure is 100 kPa (or 1 bar or 0,986 atm).

Unfortunately this convention is not universally accepted and many other STP are used.

The rules of IUPAC established standard conditions at 273,15 K (0C) and 100 000 Pa (0,9869 atm).
But other systems are also used.
