Description (last modified by naoliv)

Using the attached example file, select the outer riverbank and you see it properly measured as square kilometer.
Now select any of the inner polygons and you get the area in hectare (ha).

Both measurements should display the area in m² or Km²

That's by design, you can set one of these properties to adjust your need:

  • system_of_measurement.use_only_lower_unit to force use of squared meters
  • system_of_measurement.use_only_custom_area_unit to force use of hectares

Maybe we could another one to forbid use of hectares

Setting system_of_measurement.use_only_lower_unit I see something that, at least for me, still isn't good.
For example, I have an area here with 565517.878 m². Displaying it as 0.565518 Km² makes it easier to understand (for me).
