| 29.921 inches of mercury |
| 10.3322 meters of water |
| 406.782 inches of water |

| The unit “1 Standard Atmosphere” is defined as the pressure equivalent to that exerted by a 760 mm column of mercury at 0°C (32°F), at sea level, and at standard gravity (32.174 ft/sec2). Atmospheric pressure is the weight of a column of air per area unit as measured from the top of the atmosphere to the reference point being measured. Atmospheric pressure decreases as altitude increases. |
