Understanding Pressure Units

Pressure is force applied perpendicular to a surface per unit area. Different industries and regions use various units to measure pressure:

Common Pressure Units

  • Pascal (Pa): SI base unit, 1 Pa = 1 N/m²
  • Bar: Metric unit, approximately equal to atmospheric pressure
  • PSI: Pounds per square inch, common in the US
  • Atmosphere (atm): Based on average atmospheric pressure at sea level
  • Torr/mmHg: Based on mercury column height, used in medicine

Conversion Formulas

  • 1 bar = 100,000 Pa = 14.5 psi = 0.987 atm
  • 1 psi = 6,895 Pa = 0.0689 bar = 0.068 atm
  • 1 atm = 101,325 Pa = 1.013 bar = 14.7 psi
