14 lis 2012 · The surface of Saturn is defined by the region where the pressure of the planet reaches one bar, equivalent to the pressure at sea level on Earth. Climate and weather Like Jupiter,...

This is in contrast to mean sea-level pressure, which involves the extrapolation of pressure to sea level for locations above or below sea level. The average pressure at mean sea level in the International Standard Atmosphere is 1,013.25 hPa, or 1 atmosphere (atm), or 29.92 inches of mercury.
Convert an altitude in feet or metres of height above sea level to a pressure reading in millibar (mbar, mb or mbr), pounds per square inch (psi), millimetres of mercury at zero degrees celsius (mmHg @ 0 deg C) or inches of mercury at zero degrees celsius (inHg @ 0 deg C).
8 cze 2023 · The surface pressure of a planet is primarily determined by the mass of its atmosphere and the gravitational force acting on it. It is a measure of the weight of the overlying atmospheric column per unit area. On Earth, the standard atmospheric pressure at sea level is approximately 101.3 kilopascals (kPa), or 1 atmosphere (atm).
As with Earth's atmosphere, the pressure of Saturn's atmosphere varies with depth. Scientists define the "surface" of a gas giant as the radius at which the atmospheric pressure is equal to Earth's atmospheric pressure at sea level, i.e., 1 bar.
To calculate the air pressure at a certain altitude, use this simple formula: P = P0 × exp(-g × M × (h - h0)/(R × T) where: P0 and h0 — The pressure and altitude of the reference point. Often, these values correspond to the ones at sea level. P — The pressure at altitude h. T — The temperature at altitude h.
