A specific combination of temperature and pressure:

Temperature	293.15 K = 20 °C = 68 °F
Absolute pressure	101,325 Pa = 101.325 kPa = 1 atm = 1.01325 bar = 14.6959 psi

Also called "room conditions" or "laboratory conditions"

It should not be confused with Standard Conditions (STP) which is a different specification.
