Atmosfer Standar

Definisi

Satuan tekanan referensi yang didefinisikan tepat sebagai 101.325 pascal (101,325 kPa), mewakili tekanan atmosfer rata-rata di permukaan laut.

Penjelasan

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.
