About PSI (Pounds/sq in) and Kilopascal

PSI (Pounds/sq in) (psi)

PSI (pounds per square inch) measures pressure in pounds of force per square inch, about 6,895 pascals.

Where it's used: Tire pressures, air compressors, hydraulic systems, and plumbing in the US.

Kilopascal (kPa)

A kilopascal is 1,000 pascals.

Where it's used: Tire pressures, building wind loads, and weather systems in metric countries.

Related Specialist Pressure Calculators & Niche Tools

Pressure represents force acting over a unit of area. Standard pressure scales like PSI, bar, kilopascals (kPa), and atmospheres (atm) are utilized in HVAC, hydraulics, automotive tire inflation, and pneumatic tool operations.

Converting pressure ratings accurately is essential for equipment safety. For instance, European machinery gauges often use bar, whereas American compressors use PSI, necessitating quick conversions to prevent system over-pressurization. Our pressure calculators help technicians easily convert between scales, ensuring pressure vessels, hydraulic lines, and automotive tires are maintained at the correct operational levels.
