Pounds per Square Inch to Bar Converter

1 Pounds per Square Inch equals 0.0689476 Bar. To convert Pounds per Square Inch to Bar, divide the value by 14.5038 (multiply by 0.0689476).

To convert Pounds per Square Inch to Bar, divide the value by 14.5038 (multiply by 0.0689476). For example, 10 psi = 0.689476 bar.

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.

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

100 psi equals 6.89476 bar. To convert Pounds per Square Inch to Bar, divide the value by 14.5038 (multiply by 0.0689476).

32 psi equals approximately 2.21 bar. This is one of the most common tire pressures for passenger vehicles in the United States.

35 psi equals approximately 2.41 bar. This is a common tire pressure for SUVs and light trucks.

The recommended tire pressure for your vehicle is printed on the sticker inside the driver's door jamb (not on the tire itself). Most passenger cars run 30–35 psi (2.1–2.4 bar); SUVs typically use 35–44 psi (2.4–3.0 bar).

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.
