How do the measurements in the spatial dimensions triad (L, W, H) differ fundamentally from the physical foundation triad (L, M, T)?
Answer
Spatial dimensions are quantitatively the same type (distance), while physical units are qualitatively different.
In geometry, length, width, and height are all measures of distance (quantitatively the same type), whereas in physics, length, mass, and time are qualitatively different types of measurement (different dimensions).
