Pressure Converter - Pascal, PSI, Bar, Atmosphere and More

Convert pressure between different units instantly. Essential for engineering, meteorology, diving, pneumatics, and industrial applications.

Pressure Units

Convert between Pascal (Pa), kilopascal (kPa), megapascal (MPa), bar, millibar, atmosphere (atm), PSI (pounds per square inch), mmHg (millimeters of mercury), and other specialized units.

Pascal - SI Unit

The Pascal is the SI unit of pressure, defined as one newton per square meter. Although small for practical applications, its multiples (kPa, MPa) are widely used in engineering.

PSI in Practical Applications

PSI (pounds per square inch) is common in the US for tire pressure, pneumatic and hydraulic systems. One PSI is approximately 6,895 Pa, making it intuitive for everyday applications.

Bar and Atmosphere

The bar is close to atmospheric pressure at sea level (1 atm ≈ 1.013 bar), making it convenient for meteorology and diving. It is widely used in Europe for tire pressure and industrial systems.

Automotive Applications

Drivers convert pressure to correctly calibrate tires, following manufacturer specifications in different units, optimizing safety, fuel economy, and tire durability.

Meteorology and Climate

Meteorologists use millibars or hectopascals to measure atmospheric pressure, predict climate change, track high and low pressure systems, and communicate meteorological information.

Diving and Underwater Activities

Divers convert pressures to calculate safe depths, plan decompressions, manage air supply, and understand the physiological effects of pressure at different depths.
