2.6.1 Price comparison (PSE conversion factor)

According to the marketing law, goods in stores must be priced so that prices are easily visible to consumers. The price on the shelf must be the same as what is paid at the checkout. Additionally, a unit price must be given so that consumers can compare the price of items, regardless of packaging size.

The unit price should be calculable based on packaging unit, PSE conversion factor, and the relevant product group's price comparison unit.

Price comparison units are also used for calculations for projects by providing a conversion factor for relevant units.
