With everybody implementing cylindrical coordinate spreadsheet

My code uses rectangular coordinates (square cells in 2 dim) for
an object with cylindrical geometry. This is silly. But I am not
sure how to implement the "iterative averaging" for cylindrical
cells. So I have some questions.
For square cells we perform simple horizontal and vertical
averaging between neighbors. (4 cells in 2-dim or 6 in 3-dim).
This seems to be natural for cells of equal volume. But cells
of a cylindrical grid usually do not have that property.
1) Is it appropriate to perform simple averaging for usual
cylindrical cells (dr=const)?
2) If not then what to do? Should it be a weighted average
each time (bigger neighbor has stronger influence)?
