Pressure at a glance

Reference values

  • Standard atmospheric pressure ≈ 1 atm = 101 325 Pa ≈ 14.7 psi ≈ 1.013 bar ≈ 760 mmHg
  • 1 bar ≈ 14.5 psi — very close to atmospheric pressure
  • 1 psi ≈ 6 895 Pa ≈ 0.0689 bar
  • 1 mmHg (or torr) ≈ 133.3 Pa

Everyday pressures

  • Car tyre pressure: typically 30–35 psi (≈ 2.0–2.4 bar)
  • Bicycle tyre: often 40–80 psi (road bikes higher)
  • Blood pressure: normal ≈ 120/80 mmHg
  • Weather forecasting uses hPa or mbar — 1 hPa = 1 mbar = 100 Pa
