Convert Pounds per Square Inch to Megapascal instantly with our free online converter. 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 Megapascal (MPa) is equal to 1,000,000 pascals, used in hydraulics, material strength testing, and high-pressure engineering applications. 1 Pounds per Square Inch equals 0.00689476 Megapascal. To convert Pounds per Square Inch to Megapascal, divide the value by 145.038 (multiply by 0.00689476).

What is the correct tire pressure for a car?
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.
What pressure should a road bicycle tire have?
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.
What is normal atmospheric pressure?
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.
What is a healthy blood pressure reading?
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.
What pressure is inside a football (soccer ball)?
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.
