Bar to Pounds per Square Inch Converter

1 Bar equals 14.5038 Pounds per Square Inch. To convert Bar to Pounds per Square Inch, multiply the value by 14.5038.

To convert Bar to Pounds per Square Inch, multiply the value by 14.5038. For example, 10 bar = 145.038 psi.

The Bar (bar) is equal to 100,000 pascals, widely used for tire pressure, gas pressure, and industrial applications in Europe and internationally.

The Pounds per Square Inch (psi) is pounds per square inch — the standard pressure unit in the United States, used for tire pressure, blood pressure, and pneumatic systems.

100 bar equals 1450.38 psi. To convert Bar to Pounds per Square Inch, multiply the value by 14.5038.

Most passenger car tires are inflated to 30–35 psi (2.1–2.4 bar). SUVs and light trucks typically use 35–44 psi (2.4–3.0 bar). Always check the sticker inside your driver's door or the owner's manual for your vehicle's recommended pressure.

2.2 bar equals approximately 31.9 psi. This is a common front tire pressure for many European cars. To convert, multiply bar by 14.5038: 2.2 × 14.5038 = 31.9 psi.

2.5 bar equals approximately 36.3 psi. This is a typical rear tire pressure for many cars, especially when carrying heavier loads.

barg (bar gauge) measures pressure relative to atmospheric pressure, while bar (bar absolute) is measured relative to a perfect vacuum. In most practical conversions they are treated as equivalent: 1 barg = 1 bar. To convert barg to psi, multiply by 14.5038 — exactly the same formula as bar to psi. For example, 2.5 barg ≈ 36.3 psi.

Most passenger cars require 2.0–2.5 bar (29–36 psi) for front and rear tires. Always check the sticker on the inside of the driver's door jamb — not the number printed on the tire itself, which is the maximum pressure, not the recommended one. Pressure should be checked when tires are cold.

Road bike tires (23–28 mm wide) typically run at 6.0–8.0 bar (87–116 psi). Wider tires (32–38 mm) use 4.5–6.0 bar (65–87 psi). Mountain bike tires run much lower, at 1.5–2.5 bar (22–36 psi). The correct pressure depends on rider weight, tire width, and terrain.

Standard atmospheric pressure at sea level is 1.01325 bar, 101.325 kPa, or 14.696 psi. Weather reports use hectopascals (hPa) — a "normal" day is around 1013 hPa (1.013 bar). High pressure (fair weather) is above 1020 hPa; low pressure (storms) is below 1000 hPa.

Blood pressure is measured in mmHg (millimeters of mercury), not bar or psi. A healthy reading is below 120/80 mmHg. High blood pressure (hypertension) is defined as 130/80 mmHg or higher. For reference: 120 mmHg systolic = 0.160 bar = 2.32 psi.

FIFA regulations require a match soccer ball to be inflated to 0.6–1.1 bar (8.7–16 psi) above atmospheric pressure. Most balls are inflated to about 0.8–0.9 bar (11.6–13 psi) gauge pressure. An NFL American football is inflated to 12.5–13.5 psi (0.86–0.93 bar) gauge.
