How to get an attribute rule to calculate XY in Decimal degrees rather than the local coordinate units.

I want to have our address point automatically calculate the XY coordinates in decimal degrees whenever a new address point is created. The problem I am running into is that when I use the Geometry($feature).x/y function, it creates the point in the map coordinate system units, which is feet. Is there any way to force it to use decimal degrees?

I haven't done it for an attribute rule, but when I need a smart form to calculate latitude and longitude to populate a field, I use the script example included in this blog post: Common calculated expressions for ArcGIS Field Maps (esri.com). Scroll down to the "5. Store the geometry as an attribute" section and look at the second code block. Hope that helps!

This is what I'm going for except for the fact that it is in meters rather than feet. Although I guess I can insert a line converting the ft to meters. I will experiment with this and report back.

No matter what I do, I can't get this to work. Our data is in us feet. I cannot figure out a way to get that into meters so that it works with this script.

Is your data projected? If so, take a look at the response from @RandyBurton in this post: https://community.esri.com/t5/python-questions/feet-to-decimal-degrees-function/td-p/289896

That's a python script though, right? You can't apply that as an on the fly attribute rule, unless there is a way I am unaware of.

Yeah, true. I was thinking more that the workflow could be useful (not the specific code), but I guess it's not since there's no analagous function in Arcade yet (https://community.esri.com/t5/arcgis-pro-ideas/arcade-projectas-geometry-function/idi-p/1171382#comm...). 😞

In the meantime, maybe the Arcade code shared by @TomNeer on page two of that thread will work for you (if you are in a State Plane zone that uses Lambert conformal conic projection). If you're in a zone that uses transverse Mercator, I'm out of ideas other than upvoting that idea linked above.
