Some empirical studies have been carried out so far to identify a function able to convert IFPUG functional size units to the COSMIC ones. In this paper, we report on a replication of those studies using a dataset of 25 Web applications. As for the estimation technique, we employed linear regression analysis; while k-fold cross validation was exploited to validate the estimation models. The results show that there is a significant correlation between the size expressed in terms of COSMIC and
