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