Hello,
In this case, since the International Prototype of the Kilogram (IPK) is an object made of a platinum-iridium alloy that was used to define the magnitude of the mass of the kilogram as it weights 2.2 pounds or approximately 1 kg, yet it was replaced by a new definition of the kilogram based on physical constants. In such a way, it is important because it was the base for the current understanding of what a kilogram is and its relationship with other mass measurements.
Thus, if would not have existed, we were not be able to design and use balances or mass-measuring equipment in order to provide a reliable measure of the real mass of an object.
Best regards.
