Definition of kilogram changes from May 20, 2019- What this means
SEE ALSO :Why the fuss about intermittent fasting?This means that kilogram will be redefined based on the ratio of energy to frequency of the photon, scientifically referred to as the Planck constant. Before being voted out, a kilogram was the only SI unit still defined by a physical object. According to Science alert, Emeritus Director of the International Bureau of Weights and Measures (BIPM) Terry Quinn to Science alert says: “the idea is that having all units based on the constants of physics, they are by definition stable and unaltered in the future and universally accessible to everywhere.” Quinn also adds that the new definition aims at improving the understanding and accuracy of teaching about units. "It will open up the way to unlimited improvements in the accuracy of measurements, it will improve greatly the accuracy and extend the possibilities of making accurate measurements at very small and very large quantities," Said Quinn as quoted by science alert. To a common man, these changes make no recognizable difference since a kilogram of meat or sugar will still remain a kilogram of sugar or of meat. But in the world where accurate measurement is needed in areas such as drug development, nanotechnology and precision engineering, scientists responsible for maintaining the international system had no alternative but to phase out Le Grand K to a more robust definition.
