# Coordinate independence

Any relationship between mass, length and time in general relativity can be considered using tensors of Einstein's Field Equations which are independent of the coordinate system used and of the origin of that coordinate system

Is there a formal name for such coordinate independence and origin agnosticism? I assume there is.
