Barometer - Compensation for Altitude

Compensating manometer for elevation

Manometer - compensating for elevation

Due to decreased/increased air pressure with increased/decreased altitude the reading of barometric pressures at other elevations than sea level must be compensated.

Add compensation values to the barometric readings from the table below:

Example - Barometer reading on the top of Ben Nevis mountain, Scotland

Ben Nevis in Scotland is 1344 m high. A barometer at this elevation must be added approximately 151 mBar to compensate for the difference in pressure from sea level.
