Here we present a quatitative approach to the problem of the chromospheric emission and rotation in main sequence stars based on a consistent analysis of recent published data of stars from F8 to K5. This analysis has been performed using the following physical parameters:

a) total power emission in the Call K line, Lk;

b) stellar rotation period, Prot, from chromospheric emission variability;

c) stellar ages from lithium abundance.
