Convert between kilopascals and pounds per square inch.
The tool uses 1 psi = 6.894757293168361 kPa (exact definition tie‑in used as a double in code), so psi = kPa ÷ K and kPa = psi × K with the same constant K. Inputs must be non‑negative.
This calculator uses plain decimal numbers. If a result looks wrong, check whether you used a comma instead of a dot (or vice versa) where the field expects one.
