About pressure

Pressure is the force exerted on a specific area.

Pressure = Force / Area

The standard derived unit of pressure in the International System of Units (SI) is the pascal (Pa). Common units of pressure include atmospheres, technical atmospheres, bars, millibars, millimeters of mercury, centimeters of water, inches of water, kilopascals, pounds per square inch, pounds per square foot and torr.

Common pressure conversions

  • 1 pascal = 10-5 bar = 9.8692 × 10-6 atmospheres
  • 1 atmosphere = 1.0332 technical atmospheres = 760 torr
  • 1 pound per square inch = 6.895 × 103 pascals = 68.046 × 10-3 atmospheres
  • 1 torr = 133.322 pascals = 1 millimeter of mercury
  • 1 bar = 105 pascals = 0.98692 atmospheres
  • 1 technical atmosphere = 735.56 torr
