The need of defining quantitative and objective measures to assess the quality of a conceptual model cannot be over-emphasized. This paper proposes a set of easy-to-apply quantitative metrics which can measure the structural complexity of a given conceptual model in terms of its two important characteristics namely understandability and modifiability. Correctness of a conceptual model is identified as an important characteristic to discuss understandability. A metric for correctness is also defined. The application of these metrics is demonstrated with the help of a scenario and the resulting metrics values are compared to discuss the structural complexity of given conceptual models.
