The relation of the surface brightness, a parameter related to the apparent magnitude and the angular diameter of a star, with a colour index was first calibrated by Wesselink (1969) and later refined by Barnes & Evans (1976). This calibration has a very wide range of applicability amongst which is the evaluation of various stellar parameters. In this work, we use a number of low-mass eclipsing binaries whose parameters have been accurately determined to refine the Barnes-Evans-like relation F[V ]- (I[c]-K) introduced by Amado et al. (1999), a relation more suitable for the low temperature of cool stars.
