How unit pricing reveals value
Unit price divides the package price by its quantity. A $4.99, 32-ounce package costs about $0.156 per ounce. A $3.19, 14-ounce package costs about $0.228 per ounce, so the larger package is cheaper per ounce.
Compare like with like. Weight and liquid volume are different measurements, and a lower unit price is only useful when the product, quality, and amount you can actually use are comparable.
Reference: The NIST Unit Pricing Guide recommends consistent units so shoppers can make meaningful value comparisons.
