N2 - This paper is aimed at introducing an algebraic model for physical scales and units of measurement. This goal is achieved by means of the concept of ``positive space" and its rational powers. Positive spaces are ``semi--vector spaces'' on which the group of positive real numbers acts freely and transitively through the scalar multiplication. Their tensor multiplication with vector spaces yields ``scaled spaces'' that are suitable to describe spaces with physical dimensions mathematically. We also deal with scales regarded as fields over a given background e.g., spacetime.
