The Miller cylindrical projection is a modified Mercator projection, proposed by Osborn Maitland Miller (1897-1979) in 1942. The parallels of latitude are scaled by a factor of 0.8, projected according to Mercator, and then the result is divided by 0.8 to retain scale along the equator.[1] Hence:

(\lambda, \phi)\mapsto\left(\lambda, 1.25 \ln \tan(\pi/4 + 0.8\phi/2)\right)

where \lambda\, is the longitude from the central meridian of the projection, and \phi\, is the latitude.
