How do I know which grocery pack is better value?

Enter each pack’s final price, quantity and unit. The calculator converts grams and kilograms, or millilitres and litres, to a common unit and divides price by quantity. Results are sorted from lowest to highest price per kilogram, litre or item. Equal unit prices are identified as tied.
