How to Convert psi to bar
To convert psi (pounds per square inch) to bar, multiply psi by 0.0689476.
bar = psi × 0.0689476
Example: 100 psi × 0.0689476 = 6.89476 bar
How to Convert bar to psi
To convert bar to psi, multiply bar by 14.5038.
psi = bar × 14.5038
Example: 2 bar × 14.5038 = 29.0076 psi

About Pressure Units
Pressure is the force applied perpendicular to the surface of an object per unit area. The SI unit for pressure is the pascal (Pa), which is equivalent to one newton per square meter (N/m²).
Common Pressure Units
- Pascal (Pa): The standard SI unit of pressure, defined as one newton per square meter.
- Kilopascal (kPa): Equal to 1,000 pascals, commonly used in meteorology and engineering.
- Bar: Approximately equal to atmospheric pressure at sea level, and equal to 100,000 pascals.
- Atmosphere (atm): The average pressure at sea level, equal to 101,325 pascals.
- Pounds per square inch (psi): Commonly used in the US and UK, especially for tire pressure.
- Millimeters of mercury (mmHg): The pressure exerted by a column of mercury 1 millimeter high, commonly used in medical and meteorological applications.
- Inches of mercury (inHg): Used in weather reports and aviation altimeters in the United States.
- Torr: Named after Evangelista Torricelli, approximately equal to 1 mmHg, used in vacuum measurements.
Pressure Conversion Applications
Accurate pressure conversions are essential in many fields:
- Meteorology for weather forecasting
- Engineering systems design and fluid dynamics
- Medical applications like blood pressure monitoring
- Automotive maintenance (tire pressure)
- Aviation for altimeter settings
- Industrial processes and manufacturing
- Scuba diving for calculating safe depths
