Re-scale units of coordinates in sf geometry?
I guess the question is: "safe for what?" - if numerical errors are a problem without rescaling, then you should do it. You might be able to choose the rescaling factor such that these errors are minimized.

Is it safe to re-scale sf geometry coordinates from meters to kilometers using, for example: sfobj$geometry <- sfobj$geometry / 1000 It seems to work, but I understand too little about spatial data to know whether that practice is actually safe. I am working with spatial data in a continental-scale equidistant conic projection, and the units are meters. It seems that kilometers would be better suited stochastic partial differential equation modeling on a finite-element mesh, but maybe that is a moot point. Any and all advice will be much appreciated. Thanks!
