Accurate Altimeter measurement

How I did the measurement ?

Measure the ground level altitude at a park with digital altitude meter

Estimate the height of each floor

Using a GPS unit in the flat would produce inaccurate results use digital altitude meter

GPS units are inheritly inaccurate at altitude (compared to lateral position)

I cannot access other floors other than the one I live

I have a good view of the city. By looking at a map, I can accurately calculate my

ground-level distance to certain sea-level landmarks. These landmarks are some 5 km away.

I would like to minimize the cost of purchasing special equipment.
