we all know that kilogram is defined by the weight of a platinum-based ingot called “Le Grand K” which is safely locked in paris.
on 16-nov-2018 scientists and researchers had a meeting in Versailles to voted of it in favour of defining a kilogram in terms of an electric current.
The decision was made at theGeneral Conference on Weights and Measures.
From 1889 Le Grand K is the unit of measuring weight in international system of measuring weights .
In a world where accurate measurement is now critical in many areas, such as in drug development, nanotechnology and precision engineering.
How wrong is Le Grand K?
The fluctuation is about 50 parts in a billion, less than the weight of a single eyelash.
The pull of the electromagnet, the force it exerts, is directly related to the amount of electrical current going through its coils. There is, therefore, a direct relationship between electricity and weight.
So, in principle, scientists can define a kilogram, or any other weight, in terms of the amount of electricity needed to counteract the weight (gravitational force acting on a mass).
