About Pressure Conversion

Pressure is the force applied perpendicular to the surface of an object per unit area. It is measured in various units depending on the application.

Common Pressure Units

SI Units

  • Pascal (Pa) - The SI unit of pressure (N/m²)
  • Kilopascal (kPa) - 1,000 pascals
  • Bar (bar) - 100,000 pascals, commonly used in meteorology

Other Units

  • Pounds per Square Inch (PSI) - Common in the US for tire pressure
  • Atmosphere (atm) - Standard atmospheric pressure at sea level
  • Torr - 1/760 of an atmosphere, used in vacuum measurement
  • Millimeters of Mercury (mmHg) - Used in medicine (blood pressure)

Quick Reference

  • 1 atm = 101,325 Pa = 1.01325 bar
  • 1 bar = 100,000 Pa = 14.5 PSI
  • 1 PSI = 6,894.76 Pa
  • 1 atm = 760 torr = 760 mmHg
  • Standard atmospheric pressure = 101.325 kPa

Pressure Examples

  • Standard Atmosphere: 101.325 kPa (1 atm)
  • Car Tire: 30-35 PSI (207-241 kPa)
  • Blood Pressure: 120/80 mmHg
  • Bicycle Tire: 40-65 PSI (276-448 kPa)
  • Scuba Tank: 200-300 bar (2,900-4,350 PSI)
  • Vacuum: < 0.001 torr

Common Uses

  • Meteorology - Bar, kPa, atm
  • Automotive - PSI, bar
  • Medicine - mmHg (blood pressure)
  • Aviation - inches of mercury, millibars
  • Science - Pascal, torr
