Hi Jochen,
I forgot to mention that the "Add geometry attributes" processing
algorithm can calculate length, perimeter and area values either
planimetric in the layer's CRS (as the "length", "perimeter", and "area"
functions) or planimetric in the project's CRS or ellipsoidal (as the
"$length", "$perimeter" and "$area" functions) depending on the
"Calculate using" (CALC_METHOD) algorithm's parameter setting.
I suppose you have set the "Calculate using" (CALC_METHOD) algorithm's
parameter to "0 — Layer CRS" (which is the default value) or "1 —
Project CRS".
Regards.
Andrea

Hi Jochen,
as described in the user manual, the "Add geometry attributes"
processing algorithm [1] "generates a new vector layer ... containing
geometric measurements based on a selected CRS.", i.e. it measures
Cartesian planimetric length and area on the CRS's cartographic plane.
