Recent changes to the world's measurement system [1], [2] have been carefully designed to appear to the general public, and even to most of the scientific community, as if nothing substantial has changed. The same units exist, no new ones have been created, and the values of the properties of physical artifacts remain the same for all but the most extreme accuracies. In fact, only the definitions of the seven base units have been altered while keeping their sizes virtually unchanged. And so it might appear that these changes to our measurement system are simply a bit of tidying up and of no practical consequence to any except those few metrologists responsible for realizing and maintaining the measurement system at its highest levels of accuracy and precision.

新SI在测量领域的影响

精心设计了世界测量系统[1]，[2]的最新变化，使其对一般公众，甚至对大多数科学界来说，似乎没有实质性变化。存在相同的单位，没有创建新的单位，并且除了最极端的精度外，所有其他物理物的属性值保持相同。实际上，仅更改了七个基本单位的定义，同时实际上保持了其大小不变。因此，似乎对我们的测量系统进行的这些更改只是一些整理工作，对除了负责实现和维持测量系统的最高准确度和精确度的少数计量学家而言，没有任何实际意义。
