Atmospheric pressure from altitude Calculator
Calculates the atmospheric pressure at the present location from the altitude and temperature, and sea-level pressure. | ||
| The atmospheric pressure observed is adjusted to the equivalent sea level pressure in order to construct the isobaric weather map. If the altitude is more than 11km high above sea level, the hypsometric formula cannot be applied because the temperature lapse rate varies considerably with altitude. |

- Purpose of use
- Seeking inputs for atmospheric refraction equations -- near the horizon atmospheric refraction is a function of lapse rate in the vicinity of the observer, predominantly.
- Comment/Request
- Simple & useful, helpful that equation & its name is given!

- Purpose of use
- Watching 'Naked Science - Earth's Core'. Calculating basic pressures even at near the edge of the crust. E.g. deepest drill hole is 7.5 miles, 12000 meters deep. Try -12000m .... discover the science of our earth!

- Comment/Request
- For most occasions, I bet this is perfect. it would be great if I could do the following:
1. allow me to select units out. (yup, I can convert myself... just lazy :) )
2. Show me the formula with variables before adding values to them. What would be even better is a 1-page walkthrough of how to solve the problem on paper (for those of us who don't have a formal education)
