What determines units for measure tool in Field Maps?

[JRhodes]

Does anyone know what determines the units on the measure tool in Field Maps? I've got a map where all data is in state plane, except the Esri basemaps, which are of course Web Mercator. We want to be able to measure in feet.

Do the units of the spatial reference of the basemap determine the units in the measure tool, since the basemap determines the spatial reference of the web map?

If so, that would mean that meters are the only option when using Esri basemaps?

In the app, while on the page (the "maps" page) showing available maps, press the blue user-icon in the upper left-hand corner, and from there you can drill down into the "units" settings (under the general group) to find the "Measurement Units" which will allow you choose between automatic, US standard, and metric.

So easy, thanks.
