Abstract

Recent proposals to redefine four of the base units of the SI, including the mole, have triggered a wide- ranging debate about the terminology as well as the definitions that form the SI. Since the SI is a practical system that is used worldwide, the reasonable scope for changing it must avoid leaving large numbers of users with obsolete implementations or significantly changed values. Changes that go beyond these limits would require consultation processes that might take decades and whose cost and complexity would be difficult to justify in view of the likely benefits.
