if your data are latitude/longitude, and you specified them to be so
(i.e., is.projected(object) is TRUE), then distance is in km, else
distance is in the units of the original data coordinates.
(I recognized your output to come from gstat::variogram, but please
mention such details in future
when computing variogram, what are the units of the dist in the output
below. are they in km?
