I searched for how measure gas weight and about gases in space



Will the weight of gas measurement in space as well as in other planets of the Solar system be different as compared to gas measurement on Planet Earth?

Weight is a property of mass which you can experience only when on the solid surface of a gravitating body - but not when you are in free fall. Yet even in free fall you retain your mass. Weight is the force the mass exerts on a scale (in the presence of and proportional to the strenght of a gravity field which pushes the mass onto that scale - which requires that neither is in free fall).

Mass itself is the fundamental property of any particle itself - independent of how much other mass is in its vicinity, thus independent of external gravity field around.

See also the wikipedia article on the distinction of mass and weight.
