最近有人提议重新定义国际单位制的四个基本单位，包括摩尔，这引发了关于术语和构成国际单位制的定义的广泛争论。由于SI是一个在世界范围内使用的实用系统，因此对其进行更改的合理范围必须避免使大量用户的实现过时或价值观发生重大变化。超出这些限度的变革将需要进行可能需要几十年时间的协商进程，而且鉴于可能带来的好处，其费用和复杂性将难以证明是合理的。
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.
