Scale measurement is one of the frequently used approaches and tools for classifying micro, nano, and even macro technological application domains, despite the fundamentally significant variations in the chemical and physical mechanisms. Unit scales of macro, micro, and nano are used to understand and interpret better the size of objects in an associated and related manner at different level of scales in order to be able to understand the boundary-evading nature of materials fabricated at different levels for general and specialized fit-for-purpose applications. This book chapter focused on a relatively small portion of the larger and far-reaching field of micro/nanotechnology, which currently encompasses every aspect of science and engineering as well as anything we could possibly dream of or envision.
