kilopascals to bar table
| kilopascals (kPa) | bar (bar) |
|---|---|
| 0.5 | 0.005 |
| 1 | 0.01 |
| 2 | 0.02 |
| 5 | 0.05 |

Formula
bar = kilopascals × 0.01.
Example
10 kilopascals = 0.1 bar.
What is a kilopascal?
A kilopascal (kPa) is 1,000 pascals; tire pressure is often given in kPa.
What is a bar?
A bar is 100,000 pascals — close to average sea-level air pressure.
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 | bar |
|---|---|---|
| Atmosphere (sea level) | 101 kPa | 1.01 bar |
| Car tire (32 psi) | 221 kPa | 2.21 bar |
| Road-bike tire (80 psi) | 552 kPa | 5.52 bar |
| Espresso extraction (9 bar) | 900 kPa | 9 bar |
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.
