About Kilopascal and Pound per Square Inch

Detailed information about both units of measurement.

METRIC UNIT

Kilopascal

kPa
Definition
One thousand pascals. Commonly used for tire pressure, weather, and engineering specifications.
SI / Standard Information
SI-derived unit (kPa). 1 kPa = 1,000 Pa. The most practical metric unit for everyday pressure measurements globally.
Approximate Comparison
One kilopascal is about 0.145 PSI or roughly the pressure exerted by a 10 cm column of water.
Practical Applications
  • Tire pressure worldwide (except US)
  • Weather and atmospheric pressure
  • HVAC system static pressure
  • Hydraulic system pressure
Real-World Examples
  • Car tire pressure is typically 200-250 kPa
  • Standard atmospheric pressure is 101.325 kPa
  • A bicycle tire is about 300-450 kPa
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
