How do I convert PSI to bar?

To convert PSI to bar, multiply by 0.0689476. For example, 14.5 PSI ≈ 1 bar. PSI (pounds per square inch) is common in the US, while bar is used internationally, especially for tire pressure.

What is atmospheric pressure?

Standard atmospheric pressure at sea level is 1 atm, which equals 101,325 Pa, 1.01325 bar, 14.696 PSI, or 760 mmHg. Weather reports often reference changes from this standard.

What is mmHg used for?

mmHg (millimeters of mercury) is commonly used for blood pressure measurements and in meteorology. Normal blood pressure is around 120/80 mmHg. It's also called torr (1 mmHg ≈ 1 torr).

What is the difference between PSI and bar?

PSI (pounds per square inch) is used mainly in the US and UK, while bar is the metric unit used internationally. 1 bar ≈ 14.5 PSI. Car tire pressure is often listed in both units.

How do I read tire pressure?

Tire pressure is typically given in PSI (US) or bar/kPa (metric). Common values: 32 PSI = 2.2 bar = 220 kPa. Check your vehicle's door jamb sticker for recommended pressure.
