Altitude Versus Barometric Pressure
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) |
