Unit Price Comparator

이 도구에 대해

Stop guessing which package size is the best deal. Enter a product name, total price, quantity, and unit (kg, g, lb, oz, L, mL, fl oz, count, etc.) for each item. The comparator normalises all weights to grams and all volumes to millilitres so you can compare a 500 g jar against a 1 lb tin side by side. Results are sorted cheapest first and the best-value item is highlighted. Save your comparison lists to localStorage so you can revisit them on your next shopping trip.
