How Many Pounds is a Weight?
International Prototype Kilogram (IPK) or Le Grande K (Big K) bu This platinum-iridium mixture cylinder, stored in a safe suburb of a Parisian suburb, weighs a kilogram when weighed and may have lost its peculiar value for 126 years.
In the International System of Units (SI), scientists are trying to find a middle ground for the kilogram, which is the only unit "described" by a physical object, to lose this property. If the kilogram is expressed as a mathematical value, it will not be a more precise measure, but it will become a more stable and general-passing unit. In other words, the information about how many kilograms the actual kilogram will not be in the hands of people who can only reach the cylinder in the safe. In addition, it is much more scientific and logical to think of it as a valid “constant yerinde all over the world, rather than relying on a reference that is theoretically possible to take and lose atoms over time, with the risk of theft or disappearance, especially among the existing copies of IPK today. Even when there are differences.
After the idea of connecting the kilogram to a constant by explaining the Planck constant, the problem came to determine the Planck constant correctly. The results of a group of researchers who succeeded in converting the Avogadro constant to the Planck constant by counting the atoms in the two silicon-28 spheres of the same weight as the reference kilogram were compared to the results of the group reaching the Planck constant by means of the watt balance method, weighing the test object equivalent to the reference kilogram against electromagnetic power, A Planck constant value was agreed with a difference of 12 per billion .
Unfortunately, we need to wait for another Planck constant investigation in Russia to come to an end in order to achieve a kilogram of humanity. If everything goes well and a value close to the two studies mentioned above is found, we will have a Planck constant that we can trust. From there, give your hand a fixed kilogram .
