9,845.655ft

That's 1.87× as high as Denver, the “Mile High City”, while La Paz, Bolivia is 1.21× higher. Standard pressure there is 701 hPa (69.18 % of sea level), and water boils at 90.03 °C.

What it means

How high is that?

International Standard Atmosphere (ISO 2533), from −610 m to 20 km. Real pressure varies with weather by a few percent; temperature is the standard one, valid up to 11 km.

The math

How to convert hPa to ft

Up to 11 km: p = 1013.25 × (1 − 2.25577×10⁻⁵ × h)^5.25588 hPa; above, p falls exponentially at −56.5 °C. Boiling point by the Antoine equation for water.

Example: 701 hPa = 9,845.66 ft.
