Major supermarkets in Australia give secondary prices with a common unit for easy comparison - so a package of toilet paper might be $4.29 and in smaller text under the price will be "30c per 100 sheets" No matter how the manufacturers package or price their product a consumer can quickly look at the per-100 sheet price and pick the cheapest one. Other products might give a common price per kilogram, per 100g or per unit depending on what the product is. It's a very useful feature, especially when price is your major decision factor for a product.
