convergence factor

[kən′vər·jəns ‚fak·tər] (mapping) For a specific chart or map projection, the factor which, when multiplied by the difference of longitude between points on two meridians, will give the convergence of the meridians. Also known as convergence constant.

convergence factor

The ratio of earth convergence to a change of latitude. It is zero at the equator and maximum at the poles. Earth convergence is the angular difference between adjacent meridians at a particular position. See convergency (ii).
