What are mathematical models that translate between coordinate systems?

Transformations are the mathematical tools used to convert coordinates from one reference frame to another. They describe how data in one coordinate system maps to coordinates in a different system, and they can encompass rotations, translations, scaling, reflections, and even changes of basis. In practice, many coordinate changes are modeled as transformations, often represented by matrices (for linear changes) or affine forms that include both a matrix and a translation vector. This is why the best choice is transformations: it captures the full range of ways coordinates can be translated between systems, not just a single operation. A translation, by itself, is only a shift by a fixed amount within the same system and doesn’t cover other needed changes like rotation or scaling. Terms like evolutions or declinations aren’t standard for this concept, so they don’t fit.
