Common pressure conversion mistakes

  • Tire pressure is quoted in bar in Europe and psi in the US: 1 bar is about 14.5 psi. The recommended 2.5 bar equals about 36 psi, inflating to '25 psi' on the assumption they match leaves the tire dangerously underinflated. Multiply bar by 14.5 to get psi.
  • One atmosphere is not exactly one bar: 1 atm = 1.01325 bar = 101.325 kPa. There is also the technical atmosphere (1 kgf/cm²) at about 0.981 bar. The ~1% differences rarely matter day to day, but engineering and diving calculations need the right unit.
