Psi to bar

Psi — pounds per square inch — is the pressure unit of the United States, used for tyres, compressors, pressure washers, scuba tanks and hydraulic systems. Bar is the everyday metric unit for the same things in Europe and much of the world: one bar is 100 000 pascals, very close to atmospheric pressure at sea level. 1 psi = 0.0689476 bar, so multiply psi by 0.0689476, or divide by 14.5038.

Quick estimate

Divide by 15 and add 3 %: 30 psi → 2 + 0.06 ≈ 2.07 bar. Or remember that 14.5 psi is one bar and 29 psi is two.

  • 10 psi = 0.69 bar
  • 14.5 psi = 1 bar (about atmospheric pressure)
  • 30 psi = 2.07 bar
  • 32 psi = 2.21 bar (a common car tyre pressure)
  • 35 psi = 2.41 bar
  • 40 psi = 2.76 bar
  • 60 psi = 4.14 bar
  • 100 psi = 6.89 bar (a bicycle road tyre, a workshop compressor)
  • 150 psi = 10.34 bar
  • 3000 psi = 206.84 bar (a full scuba cylinder)

Tyres

The most common reason to convert. Car door-jamb labels in the US give psi, while pumps at European petrol stations read bar. A recommended 33 psi is 2.3 bar; over-inflating by "one unit" is far more serious in bar (14.5 psi) than in psi. Road bikes run 80–120 psi (5.5–8.3 bar), mountain bikes 25–35 psi (1.7–2.4 bar).

Gauge versus absolute

Tyre gauges read pressure above atmospheric ("gauge" pressure, sometimes written psig). Scientific and some engineering figures are absolute (psia), which includes the 14.7 psi of the atmosphere. This converter treats the number you type as-is; the factor is the same either way.

Related units

1 bar = 100 kPa = 0.987 atm = 750 mmHg. So 30 psi is also 207 kPa, the unit printed on many Japanese and Australian tyre placards.
