About Pressure Conversions
Pressure is the force applied perpendicular to the surface of an object per unit area. It's a key concept in physics, meteorology, automotive maintenance, and diving. The most common confusion arises between psi (used in the US for tires), bar (used in Europe), and atmospheres (used by divers). Doctors measure blood pressure in mmHg (millimeters of mercury). Our pressure converter handles all these units seamlessly. Key values: Standard atmospheric pressure is 1 atm, which equals 14.7 psi, 1.013 bar, or 101.3 kPa.
