Atmospheric Pressure by Altitude Calculator
Pressure (atm) = [ 1 – { ( altitude(feet) / 1000 ) / 145.45 } ]5.2561
1 atm = 760 mmHg = 14.7 psia = 1.01325 bara = 101.325 kPa
1 foot = 0.3048 m
※This is an approximate formula based on the International Standard Atmosphere model. Valid only in the troposphere (altitudes below ~11 km).
