Hi Fabricio.
Thanks for reaching out.
With the current release (4.25) it derives the units either from:
- if "view.map" created from WebScene/WebMap and user logged in it gets the units (metric or imperal) from the user's configuration.
- or from the unit of the spatial reference
At the moment it is not possible to change it on the SketchTooltipOptions directly, but this could change in an upcoming release.
In the meantime, a way to change the unit between metric and imperial is on the `view.map.portalItem`:
map.portalItem = new PortalItem({
portal: { units: "english" }
});
or if portalItem already exist with instantiating from WebMap or WebScene:
map.portalItem.units = "english"
I hope that helps.
