Yes, mass and weight are two different things. Mass is the matter contained in the body. it is a constant quantity and does not change with the position and remains constant everywhere. However weight is the force by which the Earth attracts the body towards itself. It is a variable quantity and its value changes with the change in the value of acceleration due to gravity. And if we consider g, acceleration due to gravity as 10 m/s then, a body of mass 6 kg will weigh 60 N and vice versa.
