In 2018 when the kilogram will be redefined, scientists will have developed the balance which is required for measuring: the Planck balance. This highly precise electronic weighing balance does not measure, as up to now, on the basis of the original kilogram using weights but refers to the fundamental physical constant: the Planck’s constant. The balance will be used worldwide for calibrating other scales or balances so that those correspond to the system with this new method as required.
