Pressure Converter

This free online Pressure Converter allows you to instantly convert between different units of pressure. Pressure is defined as the force applied perpendicular to the surface of an object per unit area. The SI unit of pressure is the Pascal (Pa).

Supported Units

• Pascal (Pa): The SI derived unit of pressure. 1 Pa = 1 N/m².
• Kilopascal (kPa): 1,000 Pascals. Commonly used in meteorology and tire pressure.
• Bar: A metric unit of pressure, exactly equal to 100,000 Pa.
• PSI (lbf/in²): Pound-force per square inch. Standard in the Imperial system.
• Standard Atmosphere (atm): Represents the average atmospheric pressure at sea level. 1 atm = 101,325 Pa.
• Torr (Torr): Historically based on the millimeter of mercury. 1 Torr ≈ 133.32 Pa.
