You were also never going to test your scale with a weight that is stored in a vault in Paris. So far you would test with a replica of a replica of that weight, in the best case (getting a copy directly from the local standards body). With the new definition in principle anybody can create an object that weighs exactly one kg and sell it to you.
will this increase the probability of adoption of the SI system? I have often had the impression that some nations avoided transitioning to SI out of principle, not wanting to depend on the maintenance and cooperation of another nation?
