The notion of units of measurement in science is extremely important and it therefore seems sensible to consider how this applies to digital forensics. As we will see, this does not necessarily suggest that there should be standard units of measurement in digital forensics, to report, for example, the position of the start of a file. As will be discussed later in the article, this is not always appropriate, since it is useful to describe such positions in different ways depending on the context. However, this article will discuss that reporting some unit of measurement is essential…"
