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.

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.
Worked examples
Car tyres at 33 psi. 33 × 0.06895 = 2.28 bar — set the European pump to 2.3.
A road-bike tyre at 90 psi. 90 × 0.06895 = 6.2 bar.
A 3 000 psi scuba fill. 3 000 × 0.06895 = 207 bar — a full 207-bar "aluminium 80".
Frequently asked questions
How many bar is 1 psi? 0.0689 bar. Roughly, 15 psi is one bar.
Is atmospheric pressure 14.7 psi or 1 bar? Both, nearly: 1 atm is 14.696 psi or 1.013 bar.
What is 100 psi in bar? 6.89 bar.

Bar to psi reverses this page. For kilopascals, 1 psi is 6.895 kPa and 1 bar is 100 kPa.
Good to know
Psi is also the unit on American plumbing, irrigation and espresso equipment, and on the tyre placards of cars, bikes and even wheelbarrows. Metric equipment sometimes shows kilopascals instead of bar: multiply psi by 6.895 for kPa, or convert to bar and multiply by 100. Pressure washers advertised at "2 000 psi" are 138 bar; a garden hose at 40 psi is 2.8 bar; a fire hose at 100 psi is 6.9 bar. Household water heaters and boilers have pressure-relief valves rated in psi in the US (typically 150 psi, 10.3 bar) and in bar in Europe (typically 3 bar, 43.5 psi) — not interchangeable parts.
