Similar to length classes, weight classes are used to assign weight specifications to products in the Data tab. The following information is required to create a new weight class:
Weight title: The name of the weight measurement (i.e. Kilogram)
Weight unit: The unites of measurement (i.e. kg)
Value: Set 1 for the default value.Every value added to other weights, such as g, will need to be relative to that value. There are 1000 g in 1 kg, so the value of g would be set to 1000.
