The kilogram is one of the international basic units, also one and only one which quantity can be reproduced by means of substance standard. Many scientists have worked to realize mass natural standard for several decades and have got great progress in this field. The research situation of mass natural standard in the world is summarized, the basic principle and research progress for several possible methods to realize mass natural standard are described, and the development trend of mass natural standard is given.
