Kilopascals to PSI Converter (kPa to psi)
Kilopascals (kPa) are the SI pressure unit shown on tyre placards and gauges in metric countries. One psi equals 6.89476 kPa, so divide kPa by 6.89476 to get psi.

1 kPa = 0.1450377377 psi
Calculation working
- Result = input × source factor ÷ target factor
- 1 × 1,000 ÷ 6,894.75729316836 = 0.145037737730209 psi
- Factors refer to the same base quantity. Rounding is applied to the display, not intermediate calculations.
Display: 10 significant digits. More digits do not make the original measurement more accurate.

Batch conversion
One value per line, up to 200. Uses the selected kPa → psi units. Invalid rows stay visible in the results and CSV.

Using this pressure converter
Read gauge labels and compare pressure specifications for tyres, pumps, compressors and hydraulic equipment.
Changing units preserves the pressure reference. A gauge-pressure input remains gauge pressure; an absolute-pressure input remains absolute pressure.
Check before using the result
- Unit conversion alone cannot turn gauge pressure into absolute pressure. That requires the applicable atmospheric-pressure offset.
- A unit conversion does not establish safe operating pressure. Check the manufacturer's rating and the same operating/reference conditions.
Definitions and method: NIST: unit conversion factors and rounding. Calculations use double-precision arithmetic; the display precision can be adjusted above.
