On November 16, the 26th International Metrology Conference (CGPM) adopted Resolution 1 on “Revision of the International System of Units (SI)”. According to the resolution, the definition of the mass unit "kg", the current unit "amperes", the temperature unit "Kelvin", and the unit of mass "molar" of the four SI basic units will be defined by constants and will come into effect on the World Measurement Day next year. In addition to the previous redefinition of the time unit "second", the length unit "meter" and the luminous intensity unit "candela", the first realization of the seven basic units of the international unit of measurement system is defined by the constant. This guarantees the long-term stability of SI and the universality of the environment. It will also open the door to anytime, anywhere, and any subject to reproduce the unit value according to the definition. It can be said to be a milestone in the progress of human science.

      After the original forecast, the supervision of measuring instruments will cancel the cycle and regular traceability methods, and only the supervision and spot check verification (sampling verification, calibration). It seems that this is also superfluous, and the transmission and traceability of the values will become history. All the 7 basic units have realized the definition of constants. With the help of intelligent intelligent technology, the measurement of magnitude will get a big leap forward. Through chip technology, instrumentation can realize self-calibration. The method of periodic and periodic traceability measurement is lost. Sex, the use of measuring instruments, periodic verification, calibration will become history. There are also survival crises in the measurement institutes of provinces, cities and counties. Bold prediction: Measurement business will become history after ten years.
