Pressure Converter

Pressure is defined as the force applied perpendicular to the surface of an object per unit area. It is a critical parameter in fields ranging from meteorology and aviation to automotive engineering and fluid dynamics.

This professional converter bridges the gap between the scientific Metric (SI) system—based on the Pascal—and the practical units used in daily industry, such as psi for tire pressure, bar for industrial machinery, and atm or mmHg for atmospheric conditions.

Common Uses

Different industries rely on specific pressure units for historical reasons:

  • Pascal (Pa): The SI base unit, used in physics. Often seen as kPa or MPa in engineering.
  • PSI: “Pounds per Square Inch” is the standard for tire pressure, hydraulics, and plumbing in the US.
  • Bar: Approximately equal to atmospheric pressure at sea level. Commonly used in meteorology and SCUBA diving.
  • mmHg / Torr: Used in medicine (blood pressure) and vacuum physics. 1 Torr is exactly 1/760 of an atmosphere.
