Comment on NIST to redefine the kilogram based on a fundamental universal constantparentComments−johncolanduoni9yThe simple platinum cylinder's margins of error are pretty much unbounded over time. If you come up with a good physical definition, our knowledge of the value will only get more precise over time as the means for measurement are improved.
