How this calculator helps

Supermarkets often print unit prices, but marketplaces may not. This tool recreates the comparison for any two packages with the same measurement basis.

Formulaunit price = price ÷ size, compare unit prices

Common mistake

Do not mix grams and ounces without converting first. Both sizes must be expressed in the same unit.
