This material is rarely discussed in the literature. The task of forming a holistic idea of the origin of the main physical units of measurement is posed. Materials and Methods: Modern measurements of physical quantities use two main international systems of units â Metric and SI, historically related to each other. The method of calculating new standards of radio engineering units of measurements based on modern scientific and technical achievements and fundamental physical constants is discussed. The value for the corrected mass is -0.078.Ä«ackground and Objectives: The article discusses the methodological recommendations for teachers and experimental researchers on metrological support of measurements and the correct use of units of physical quantities when reading courses in the theory of communication and radio measurements and conducting practical classes. The measurement result is equivalent if -1 ![]() The correction that arises due to air buoyancy while weighing in the air is -0.00115 g and is greater at higher density. The air buoyancy correction value is obtained by determining the air density using the CIPM-2007 formula. ![]() ![]() Therefore, the correction of air buoyancy is very important. By Archimedes' law, the buoyant force generated by the air due to this density difference is huge. In this study, the E0 no 74 made of stainless steel has a density of 8.051.130 kg.mâ3 calibrated by a mass standard of Pt-Ir which has a density of 21.552.940 kg.mâ3. This is caused by a significant difference in the density of standards. Determination of the mass value of E0 no 74 by calibrating it using the Pt-Ir standard has high complexity.
