# Formula Barometric Formula Pressure    Pressure at the bottom    Scale height    Height

## Pressure

Unit
Air pressure (or the pressure of another fluid) at height $$h$$ above the sea surface. According to this barometric formula, air pressure decreases exponentially with height.

## Pressure at the bottom

Unit
Air pressure at sea level $$h = 0$$.

## Scale height

Unit
Scale height is a constant that depends, for example, on the temperature of the air and the gravitational acceleration. The scale height is approximately $$H=8\,\mathrm{km}$$ on Earth.

## Height

Unit
Height measured from the sea surface.
