Supermarkets love the “family size” illusion: a bigger box at a higher price that quietly costs more per ounce. Shelf tags sometimes show unit prices, but they are tiny, inconsistent, and often missing exactly when you need them.
Enter each product’s price, size, and unit — ounces, pounds, grams, kilograms, milliliters, all accepted and mixed freely — and the calculator standardizes everything to one comparable unit price. The better deal is highlighted, so the answer is obvious at a glance.

FAQ
What units are supported?
Weight: oz, lb, g, kg. Volume: ml, L, fl oz, cup, pint, quart, gallon. Mix them freely — everything converts to a common base.
Why not just read the shelf tag?
Shelf tags are often missing, hard to read, or use inconsistent units between brands. This gives you one clean comparison in seconds.
Can I compare more than two products?
The side-by-side view compares two at a time, which covers the usual “store brand vs. name brand” decision. Run it again for a third contender.
