Standard Temperature and Pressure

Standard temperature and pressure (STP) is a temperature 0ºC (32ºF) with the air pressure the same as at sea level.

SATP- Standard Ambient Temperature and Pressure

Temperature: 25 degrees celsius

Pressure: 101.32 kPa

It is important for the comparison of experiments and the determination of properties to have identical conditions.

Standard conditions, or standard temperature and pressure (STP) is the atmospheric pressure at sea level with temperature at zero degrees Celsius (273.15 Kelvin).
