Altitude Versus Barometric Pressure
WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.
Determine the current vehicle testing altitude.
The following table illustrates the relation between altitude and barometric pressure:
| Altitude | Barometric Pressure |
|---|---|
| 4, 267 m (14, 000 ft) | 56 to 64 kPa (8.1 to 9.3 PSI) |
| 3, 962 m (13, 000 ft) | 58 to 66 kPa (8.4 to 9.6 PSI) |
| 3, 658 m (12, 000 ft) | 61 to 69 kPa (8.8 to 10.0 PSI) |
| 3, 353 m (11, 000 ft) | 64 to 72 kPa (9.3 to 10.4 PSI) |
| 3, 048 m (10, 000 ft) | 66 to 74 kPa (9.6 to 10.7 PSI) |
| 2, 743 m (9, 000 ft) | 69 to 77 kPa (10.0 to 11.2 PSI) |
| 2, 438 m (8, 000 ft) | 71 to 79 kPa (10.3 to 11.5 PSI) |
| 2, 134 m (7, 000 ft) | 74 to 82 kPa (10.7 to 11.9 PSI) |
| 1, 829 m (6, 000 ft) | 77 to 85 kPa (11.2 to 12.3 PSI) |
| 1, 524 m (5, 000 ft) | 80 to 88 kPa (11.6 to 12.8 PSI) |
| 1, 219 m (4, 000 ft) | 83 to 91 kPa (12.0 to 13.2 PSI) |
| 914 m (3, 000 ft) | 87 to 95 kPa (12.6 to 13.8 PSI) |
| 610 m (2, 000 ft) | 90 to 98 kPa (13.1 to 14.2 PSI) |
| 305 m (1, 000 ft) | 94 to 102 kPa (13.6 to 14.8 PSI) |
| 0 m (0 ft) | 96 to 104 kPa (13.9 to 15.1 PSI) |
| -305 m (-1, 000 ft) | 101 to 105 kPa (14.6 to 15.2 PSI) |
