[R-sig-Geo] Re-scale units of coordinates in sf geometry?

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!
