How pressure conversion works
Pressure conversions go through the pascal, one newton per square meter. A bar is exactly 100,000 Pa, and a standard atmosphere is 101,325 Pa, about 14.696 psi or 760 mmHg.
Tire pressures are quoted in psi in the US and in bar or kPa in Europe: 32 psi is about 2.2 bar or 221 kPa. Blood pressure is still measured in millimeters of mercury.
