What is UMS and why convert it?
UMS (Uniform Mark Scale) is how Cambridge standardises scores across different exam sessions and syllabus variants, so a UMS score means the same thing regardless of which year or version of a paper you sat. Converting UMS to a plain percentage makes it easier to compare your performance or use it in aggregate calculations that expect a percentage.
