All barometric pressures (like those seen on the weather reports) are converted to mean sea level (MSL) pressures. This handy calculator does the same as long as you know your actual physical elevation above sea level. This calculator is in metric units.
| variable | description |
| temperature | the current station temperature |
| atmospheric pressure | the current station barometric pressure |
| elevation | the actual elevation above sea level of the station |
| mean sea level pressure | calculated barometric pressure with sea level as the reference point |
