Scale Point

A scale point is the smallest unit of measurement used internally for typesetting, defined as of a point. Since a single point is of an inch, a scale point is approximately of an inch. The fine granularity allows TeX to represent dimensions with high precision, using fixed-point arithmetic to avoid rounding errors and ensure consistent results across systems.
