Would an object weigh more or less in vacuum?

An object will weigh more in vacuum than in air because of the upthrust. There is no upthrust in vacuum whereas in air the pressure pushes an object or person from all sides. The air is dense and it is similar like water where the weight of an object is equal to the weight of the water displaced by it.
