A 500 g bag priced at 3 costs 6 per kg. A 1 kg bag priced at 5 costs 5 per kg, which is 16.67% cheaper per kilogram. For six 330 mL cans, enter 330 mL and 6 packs, with the total price of the six-pack.

Mass results use kilograms; volume results use liters. Ounces (oz) measure weight, while US fluid ounces measure volume. Gallons are US liquid gallons, not Imperial gallons. Mass and volume cannot be converted without density. Compare items of equivalent size and quality; lowest unit price does not necessarily mean lowest total spend.
