Pressure Unit Converter
Convert pressure values between different units like Pascal, Bar, PSI, and more.
About Pressure Units
Pressure is the force applied perpendicular to the surface of an object per unit area. Different pressure units are used in various fields including engineering, meteorology, and everyday applications.
Common Pressure Units
- Pascal (Pa) - The SI unit of pressure, equal to one newton per square meter (N/m²)
- Kilopascal (kPa) - Equal to 1,000 pascals, commonly used in meteorology
- Bar - Approximately equal to atmospheric pressure at sea level, equal to 100,000 pascals
- PSI (Pounds per Square Inch) - Common in US and UK for tire pressure, equal to 6,894.76 pascals
- Atmosphere (atm) - Standard atmospheric pressure at sea level, equal to 101,325 pascals
- Torr/mmHg - Named after Evangelista Torricelli, almost equal to one millimeter of mercury
- Inch of Mercury (inHg) - Used in aviation and weather reporting in the US
Pressure Conversion Applications
- Engineering - Converting between units for specifications and designs
- Weather forecasting - Converting barometric pressure readings
- Aviation - Converting altimeter settings and atmospheric pressures
- Automotive - Converting tire pressure specifications
- Medical - Converting blood pressure readings
Example
Converting standard atmospheric pressure:
- 1 atmosphere (atm) = 101,325 Pa
- 1 atmosphere (atm) = 1.01325 bar
- 1 atmosphere (atm) = 14.6959 psi
- 1 atmosphere (atm) = 760 mmHg (or Torr)
These conversions are useful when working across different measurement systems.
