The products of sea-level factor times scale factor is called:

In map calculations, distances on the grid must account for both how the projection stretches space (the scale factor) and any adjustment related to sea level or vertical height (the sea-level factor). When these two effects are multiplied, they give the grid factor—the overall conversion factor between a distance on the grid and the actual ground distance. This combined factor is what you use to translate grid measurements into real-world distances, and to understand how grid spacing corresponds to geography. The other terms don’t capture this combined effect: a gridline factor would refer to the gridlines themselves, a sea-level factor alone is just the height adjustment, and the scale factor alone doesn’t incorporate the sea-level component.
