Formula
psi = kilopascals × 0.145038.
Example
10 kilopascals = 1.45038 psi.
What is a kilopascal?
A kilopascal (kPa) is 1,000 pascals; tire pressure is often given in kPa.
What is a psi?
Pounds per square inch (psi) is the imperial pressure unit (tires, etc.).
Real-world reference points
Sea-level air is ~1 bar (14.7 psi); car tires run ~2.2 bar (32 psi); espresso machines ~9 bar.
| Reference | kilopascals | psi |
|---|---|---|
| Atmosphere (sea level) | 101 kPa | 14.7 psi |
| Car tire (32 psi) | 221 kPa | 32 psi |
| Road-bike tire (80 psi) | 552 kPa | 80 psi |
| Espresso extraction (9 bar) | 900 kPa | 131 psi |
Mistakes to avoid with pressure conversions
- Mixing gauge and absolute pressure: tire gauges read pressure ABOVE atmospheric (psig), not absolute (psia).
- Inflating tires to the sidewall maximum instead of the door-jamb recommendation.
- Confusing bar with psi — a 2.2 vs 32 mixup is a dangerous under/over-inflation.
