About Pressure Conversion

Pressure is the force applied perpendicular to a surface per unit area. The SI unit is the pascal (Pa), equal to one newton per square meter. Because the pascal is a very small unit, kilopascals (kPa) and megapascals (MPa) are commonly used in engineering and industrial applications. The bar (100,000 Pa) is widely used in meteorology and industry across Europe.

In the United States, pounds per square inch (psi) is the dominant unit for tire pressure, hydraulic systems, and HVAC applications. One standard atmosphere (101,325 Pa or 14.696 psi) represents the average air pressure at sea level. Millimeters of mercury (mmHg) and torr are essentially equivalent and are used extensively in medicine for blood pressure readings and in vacuum technology.

Understanding these different pressure units is critical in fields ranging from automotive maintenance and scuba diving to weather forecasting and chemical engineering, where pressure readings from different standards must be compared accurately.
