Standards Based on Fundamental Physical Constants

The article discusses the current trend in metrology the use of fundamental physical constants to create standards of basic units of measurement. This approach ensures maximum accuracy and reliability of reproducing reference units in any laboratory equipped with the necessary equipment. The authors consider all existing units of measurements in the International System of Units (SI) and discuss modern approaches to creating measurement standards based on fundamental physical constants. The authors define the existing units of measurement and analyze the advantages of using fundamental physical constants to improve the accuracy and stability of measurements in various fields of science and technology. The current achievements in the field of metrology related to the transition from traditional standards to more universal and reproducible standards are presented. In conclusion, the article emphasizes the importance of choosing standards based on fundamental physical constants and provides their advantages.
