A formula is a type of product configuration element used when products are configured.
Formulas are defined by the user. They can contain attributes features, fixed numeric values from the item, bill of material or routing, drawing measurements, and ordered quantities.
Boolean algebra and trigonometric functions can be used when creating formulas. One formula can also give multiple results; for example, both length and width can be calculated from the same formula.
Formulas are mainly used to calculate quantities, run times, drawing measurements and sales and purchase prices.
Formulas also are used for calculated quality tests in the Quality Management System (QMS). For more details, refer to the following document: Calculated Quality Tests
