Formula
kilopascals = psi × 6.89476.
Example
10 psi = 68.9476 kilopascals.
What is a psi?
Pounds per square inch (psi) is the imperial pressure unit (tires, etc.).
What is a kilopascal?
A kilopascal (kPa) is 1,000 pascals; tire pressure is often given in kPa.
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 | psi | kilopascals |
|---|---|---|
| Atmosphere (sea level) | 14.7 psi | 101 kPa |
| Car tire (32 psi) | 32 psi | 221 kPa |
| Road-bike tire (80 psi) | 80 psi | 552 kPa |
| Espresso extraction (9 bar) | 131 psi | 900 kPa |
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.
