Box 1: Standard

Standard conversions – Set up standard conversion rules for all products.

Box 2: Intra-class

Crayons are stored as separate item numbers depending on whether they are in a box or a case. This creates issues when counting inventory to determine the total number of crayons in stock.

Intra-class conversions – Set up product-specific conversion rules for units in the same unit class. For example, you can set up a conversion rule for a product that converts a box to the number of pieces in a box. Pieces and boxes are both assigned to the Quantity unit class.

Incorrect:

Inter-class conversions – Set up product-specific conversion rules for units across unit classes. For example, you can set up a conversion rule for a product that converts kilograms to liters. Kilograms are assigned to the Mass unit class and liters are assigned to the Liquid volume unit class.
