4Industrial engineering (MPa, bar)

Pressure conversion — common questions

What's the difference between bar and psi?

1 bar = 100,000 Pa ≈ 14.504 psi. Bar is metric/SI-friendly; psi is US imperial. Tire pressure in cars is commonly 30–35 psi or ≈ 2.1–2.4 bar.

Is 1 atmosphere the same as 1 bar?

Very close but not identical. 1 atm = 1.01325 bar = 101,325 Pa. 1 bar = 100,000 Pa.

Why is blood pressure in mmHg?

Historically measured with mercury manometers — the pressure that supports a column of mercury that many millimetres tall. 120 mmHg systolic ≈ 16 kPa.
