Software metrics refers to a broad range of measurements for computer software. Software metric is a mathematical definition mapping the entities of a software system to numeric measurement values. Measure the software and the software development processes both are very important for organization. As we know when we are calculate software metrics by different-different tools the result will differ due to metrics tools use different methodology. The results are thus tools dependent and are in question for validations. Here an attempt is made to integrate eight different object oriented free metric tools. A study has been done to measure the metrics values using the same set of standard metrics for a software projects. The results have been discussed before and showed the variations in results from different tools for same metrics. Measurements show that, for the same software system and metrics, the metrics values are tools dependent. In this study we have considered comparison of CCCC, CKJM, Dependency Finder, Semmle, VizAnalyzer, JHawk Tool, Analyst 4j and OOMeter Tools.
