I'm working on MUIMapparium and want to show the length of a track also in imperial units. I found the loc_MeasuringSystem with Values MS_ISO, MS_IMPERIAL, ... but I did not found how to change that Value in MorphOS (same on AROS/Amiga). I did expect the Country setting would influence that, seems I was wrong.
Anyone has an idea?

Thanks for help.

Seems no-one care to answer, so I answer myself.

It seems it's not implemented. I guess MorphOS share AROS locale source? I found in the AROS source that the value is never set, even the setting is present in country settings.
I made a patch and sent to AROS ML and hope to get it included so later versions will fix that.

Thank you very much! I did the AROS check-in.
Nevertheless I reported the bug in MorphOS' bug tracker.
