Unit Price Comparator

Compares the real price paid per product (already including discounts or coupons applied) normalized to a base unit of mass, volume, length, area, or quantity, reusing this suite's unit converter. It never converts mass to volume or vice versa without you providing a factor: each unit category is compared only against itself.

Frequently asked questions

Does it automatically convert between mass and volume?

No, unless you enter a density; mass and volume are always compared within their own category.

Is the cheapest option always the best quality?

No. Price per unit doesn't measure quality; the tool states this explicitly.
