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)
