Pressure conversion — common questions
What's the difference between bar and psi?

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.
