Feet to hectopascals
Type a value in ft to get it in hPa instantly.
That's 1.86× as high as Denver, the “Mile High City”, while La Paz, Bolivia is 1.21× higher. Standard pressure there is 701.2 hPa (69.2 % of sea level), and water boils at 90.03 °C.
Convert the other way: hPa to ft
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 ft to hPa
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: 9,840 ft = 701.154 hPa.
