Conservation of mass definition is - a principle in classical physics: the total mass of any isolated material system is neither increased nor diminished by reactions between the parts —called also conservation of matter. But weight is caused by gravity, so your weight on the Moon is less than here on Earth, while the mass stays the same. However, due to the ambiguity surrounding the definition of matter itself, this definition greets a lot of criticism. Under the influence of the Kantian formulation, often incompletely understood, and primarily owing to the fact that in spite of the universal use of the concept in science as well as in philosophy no clear-cut definition of mass was available, most authors defined mass as quantity of matter without specifying how to measure it.
