Elevation above sea level and air temperature, pressure and density.
Standard values for pressure, temperature and density (ignoring the slight effect of humidity) at altitudes from
sea level to 16,000 feet (about 4900 m):
density - % of density at sea level
1 ft (foot) = 0.3048 m
1 in mercury (Hg) = 3,376.8 N/m 2 (Pa)= 0.49 lb/in 2 (psi) = 12.8 in water
T( oC) = 5/9[T( oF) - 32]
