Understanding Pressure Units

The Pascal (Pa)

Key concepts:

  • SI unit of pressure
  • 1 Pa = 1 N/m²
  • Named after Blaise Pascal
  • Used in fluid mechanics
  • Modern scientific standard

Atmospheric Pressure

Important facts:

  • Standard pressure: 1 atm
  • Equals 101,325 Pa
  • Varies with altitude
  • Weather indicator
  • Affects boiling points

Altitude Effects

Pressure changes:

  • Sea level: 1013.25 hPa
  • -12% per 1000m rise
  • Affects air density
  • Aviation impacts
  • Biological adaptations

Essential Pressure Conversion Formulas

Basic Conversions

1 atm = 101,325 Pa

1 Pa = 9.8692 × 10⁻⁶ atm

Barometric Formula

P = P₀e^(-mgh/RT)

h = -(RT/mg)ln(P/P₀)
