About Atmosphere and Pound per Square Inch

Detailed information about both units of measurement.

SCIENTIFIC UNIT

Atmosphere

atm
Definition
Standard atmospheric pressure at sea level, equal to 101,325 pascals.
SI / Standard Information
Defined as exactly 101,325 Pa. The atmosphere is a convenient reference unit for pressure in chemistry, physics, and diving.
Approximate Comparison
One atmosphere is the average pressure exerted by Earth's atmosphere at sea level.
Practical Applications
  • Chemistry and gas law calculations
  • Scuba diving decompression tables
  • Deep-sea and high-altitude research
  • Vacuum system comparison
Real-World Examples
  • 1 atm is the pressure at sea level
  • At 10 meters underwater, pressure is about 2 atm
  • Mount Everest summit pressure is about 0.33 atm
IMPERIAL UNIT

Pound per Square Inch

psi
Definition
Pounds of force per square inch. The US standard for tire pressure, hydraulics, and engineering.
SI / Standard Information
Defined relative to Pa: 1 psi ≈ 6,894.76 Pa. The primary pressure unit in US automotive, industrial, and engineering contexts.
Approximate Comparison
One PSI is about 6.9 kPa or roughly the pressure of a tall drinking straw full of water.
Practical Applications
  • US tire pressure measurement
  • US hydraulic system pressure
  • US water system pressure
  • US HVAC refrigerant pressure
Real-World Examples
  • Car tire pressure is typically 30-36 PSI
  • Home water pressure is about 40-60 PSI
  • A hydraulic press might operate at 3,000-10,000 PSI
