Atmósfera Estándar

Definición

Una unidad de referencia de presión definida exactamente como 101.325 pascales (101,325 kPa), que representa la presión atmosférica media aproximada al nivel del mar.

Explicación

Standard atmosphere (atm) is used to define other pressure units: 1 atm = 760 mmHg = 14.696 psi = 1.01325 bar. A typical car tire is inflated to 2.2–2.5 atm gauge pressure (above atmospheric). Deep-sea submersibles must withstand more than 1,000 atm at 10 km depth. The standard atmosphere is also the upper boundary of ‘Standard Conditions’ in gas law calculations.
