Altitude-Pressure Tables Based on the United States Standard Atmosphere

The altitude-pressure tables of the United States standard atmosphere given in Technical Report No. 246 (reference 1) are reprinted since that report is out of print. Advantage is taken to make certain revision in the text and particularly to extend the altitude range of the tables from 50,000 to 80,000 feet. These tables include: (I) Altitude in feet at pressure intervals of 0.1 millimeter of mercury in the range 20 to 200 millimeters of mercury and at intervals of 0.2 millimeter of mercury in the range 200 to 790 millimeters of mercury; (II) altitudes in feet at pressure intervals of 0.01 inch of mercury in the range 0.8 inch lo 31.09 inches of mercury; and (III) pressures in both millimeters and inches of mercury and air temperatures for every 500-foot interval in the altitude range -1,000 to 60,000 feet and for every 1,000-foot interval up to 80,000 feet. The mean temperature of the air column is given for each of the altitudes in table III up to 50,000 feet.

The work was carried out at the National Bureau of Standards, in part with the cooperation and financial assistance of the National Advisory Committee for Aeronautics.
