Embodiments of the present disclosure relate to processes and software used to standardize the calculation of the weight and CG of a product. The processes and software integrate data from multiple sources and confirm the accuracy of the data. The software program standardizes the calculation of weight and CG by using a central calculation worksheet accessible to all users tasked with determining the weight and balance of a product. The software includes functionality for viewing Bill of Material (BOM) and 3D images, for operating a calculation worksheet, for storing and filtering data, and for reporting data.
