Relative height values to absolute ones

[mnovara]

Hello everybody !

I´d like to know if it is possible (via some mathematic formula) to convert the relative values that we obtain in our flights, to absolute ones, knowing the absolute height of the take off spot.

Thank you in advance !

What about just *adding* both values??
