Standard Temperature and Pressure (STP) is a reference point used in various scientific fields, including chemistry and physics, to provide a common baseline for measurements and calculations. The commonly accepted values for STP are:
- Standard Temperature: 0 degrees Celsius (273.15 Kelvin)
- Standard Pressure: 1 atmosphere (atm), which is equivalent to 101.325 kilopascals (kPa) or 760 millimeters of mercury (mmHg).
STP conditions are often used to calculate the properties of gases, such as volume or molar volume, and are also important in defining standard conditions for reactions and experiments.
