Kilopascals to Pounds per Square Inch Converter

Convert Kilopascals (kPa) to Pounds per Square Inch (psi) instantly.

Unit: kPa

Unit: psi

Formula: psi = kPa × 0.145037737730209(editable from both sides)

Kilopascals to PSI: tire and equipment pressure conversion

Convert kPa to PSI for tire pressure, hydraulic systems, and equipment specs. Both units are common in automotive and engineering contexts.

Formula

The formula is psi = kPa × 0.145038. Multiply kilopascals by 0.145038 to get pounds per square inch.

Worked example

200 kPa = 200 × 0.145038 = 29.01 PSI. This is a typical tire pressure for passenger vehicles.

300 kPa43.51 psi

Practical guidance

Tire pressure

Vehicle manuals may list tire pressure in kPa or PSI depending on the market. Converting ensures you inflate to the correct pressure regardless of the pump gauge units.

Hydraulic systems

Hydraulic machinery uses pressure ratings in both units. Converting ensures compatibility when replacing components or reading gauges from different manufacturers.

Mistake: dividing by 7

Dividing kPa by 7 is a rough estimate but gives 28.6 PSI for 200 kPa instead of 29.01. Use 0.145038 for precision.
