Therefore, since the curvature of the universe is essentially set by its expansion rate, the expansion rate of the universe determines how far away assuming special relativity works (which is typically as far as the expansion is negligible, so within a megaparsec or so, and also far away from any really dense objects, such as black holes or neutron stars).
