120v from hot to ground on receptacle ?

Changing out outlets in the add on room, and found an outlet that will read 120 from the hot to ground and 120 hot to netural. Even hot to the metal j box gives ke 120 reading. Is this ok ? The only outlet so far in the house that does that. The wiring in this room is ypdated, it has 2 wire with a bare ground wire. Rest of the house is 1951 2 wire, no ground.

Those are the correct readings for a correctly installed branch circuit with ground.

As Ray posted, that is the way it should be. It also means that all of the rest of your receptacles should either be two-prong (no equipment ground connection) or they should be fed from a GFCI (ground fault circuit interrupter) which could be a GFCI receptacle properly wired or a GFCI circuit breaker. Any GFCI receptacle that does not have a proper equipment grounding conductor must be labeled No Equipment Ground.
