Стандартная атмосфера

Определение

Эталонная единица давления, равная ровно 101 325 Па (101,325 кПа), представляющая приблизительное среднее атмосферное давление на уровне моря.

Объяснение

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.
