Convert pressure from bar to psi or from psi to bar. Also shows kPa and MPa.
Enter your values, then select Calculate.
psi = bar × 14.5038. bar = psi × 0.0689476 (psi ÷ 14.5038). 1 bar = 100 kPa = 0.1 MPa.
The result keeps the same pressure reference: gauge stays gauge (barg to psig) and absolute stays absolute (bara to psia). Factors follow the NIST table.

This bar to psi converter changes pressure from bar to pounds per square inch (psi) and back. Use it for tyre pressure, compressed air, hydraulic systems, pressure gauges and instrument ranges.
psi = bar × 14.504
Example: 2.5 bar × 14.504 = 36.3 psi. A compressed air system at 7 bar is at 101.5 psi.
bar = psi × 0.068948 (or psi ÷ 14.504)
Example: 35 psi ÷ 14.504 = 2.41 bar. A 100 psi line is at 6.89 bar.

Most gauges read gauge pressure (barg, psig): the pressure above the surrounding atmosphere. Absolute pressure (bara, psia) adds atmospheric pressure, about 1.013 bar or 14.7 psi at sea level.
bara = barg + 1.013; psia = psig + 14.7
Convert gauge to gauge and absolute to absolute: 6 barg = 87.0 psig, and 7.013 bara = 101.7 psia. The converter keeps whichever reference you enter.
| Application | bar | psi |
|---|---|---|
| Standard atmosphere (absolute) | 1.013 | 14.7 |
| Car tyre (typical) | 2.2–2.5 | 32–36 |
| Domestic water supply (typical) | 2–4 | 29–58 |
| Workshop compressed air | 6–7 | 87–102 |
| Industrial compressed air main | 7–8 | 102–116 |
| Pressure washer | 100–150 | 1,450–2,175 |
| Hydraulic system | 150–350 | 2,175–5,075 |
Choose bar to psi or psi to bar, enter the pressure and select Calculate. The result also shows kPa and MPa. For other units such as kPa to psi, use the pressure unit converter.
Multiply bar by 14.504. For example, 3 bar × 14.504 = 43.5 psi.
Divide psi by 14.504, or multiply by 0.068948. For example, 100 psi = 6.89 bar.
1 bar is 14.504 psi.
2.5 bar is 36.3 psi. That is a common car tyre pressure.
35 psi is 2.41 bar.
10 bar is 145 psi.
Both are gauge pressures, meaning pressure above atmosphere, but in different units. 1 barg = 14.5 psig. Add atmospheric pressure to get absolute pressure: 1 barg = 2.013 bara = 29.2 psia.
Nearly. 1 standard atmosphere is 1.01325 bar, or 14.696 psi.
