Scientists abandoned the use of the standard kilogram

Ученые отказались от использования эталона килограмма

Copies of the standard kilogram

The new system will allow us to determine the pounds of anyone who has a device called the balance of the Kibble.

The participants of the General conference on weights and measures in Paris have changed the definitions for the four units of the International system of physical units, including pounds. As Radio liberty reports, the scientists abandoned the use of the standard kilogram, now this value will be determined using Planck’s constant.

It is noted that every few decades all copies of the kilograms in the world had to be checked. The new system will allow us to determine the pounds of anyone who has a device called the balance of the Kibble. It measures the amount of electrical current needed to create the electromagnetic field equal to the force acting on the chosen mass. The mass of an object is found from the equality of electric and mechanical forces. Any country can use the balance of the Kibble and won’t need the reference kilogram.

A complete rejection of the use of the standard kilogram held in may next year. Up to this point, the kilogram remains the only unit for which physical standard is still used.

After binding to the Planck constant reference pounds will not be as much weighing – the weight of the cylinder will differ from a kilogram of ±10 micrograms.

Previously, scientists said that human evolution is not only not ceased, but continues with greater speed.
